Science Supporting Natural Penis Enlargement – Studies, etc.

natural penis enlargement proof1 e1443725112509 300x270 Science Supporting Natural Penis Enlargement   Studies, etc.Penis enlargement is synonymous with the word “scam”.

Seems like the two go hand-in-hand in most people’s minds.

However, although male enhancement pills make ridiculous, untruthful claims, manual penis enlargement exercises DO work.

I’ve increased my penis size with the manual techniques, as have the men I learned PE from, as have the thousands of men who’ve read my guide. So I, for one, know it works… but it’s been a LONG time, and science still hasn’t done any large scale studies on manual penis enlargement techniques.

And if you were to go to your doctor and ask him “Hey Doc, can I make my penis bigger with these exercises?”

Without a doubt, you’ll get a warning to stay away… this is due to a doctor’s fears of being liable for some damage, and receiving a malpractice suit. It’s due to ignorance, but it’s not their faults… science hasn’t been too adamant about studying this stuff.

(Funny note, I know a couple of doctors who actually do penis enlargement themselves, including one man who was in his 70’s and loved the exercises due to the massive flaccid hang it gave them. He’d brag about being the biggest in the nude beaches he’d frequent).

However, when it comes to science supporting penis enlargement, there are some studies and surveys out there that support our cause…

Survey of 545 Men And Their Natural Penis Enlargement Results

Back in 2008, a survey of 545 men was carried out on the now defunct

While the site is no longer up, I came across this study back then, and wrote down the findings in my notes:

  • Top gainers were able to gain 1 inch in length and half an inch in extra girth in 3 months of performing the exercises
  • Out of the 545 men, only 7 felt that penis enlargement exercises did not work
  • Men who ejaculated less gained more
  • The majority of men experienced stronger and harder erections
  • The amount of time put in correlated to gains made

While surveys are not without their flaws, and this would been better in a more controlled setting, seeing repeating results in a large group is indeed strong anecdotal evidence.

Study On Men Using Extension Devices Shows Increase In Penis Size Possible

In a 2011 study published in the Journal Of Sexual Medicine, after 3 months of wearing an extension device for several hours a day, men showed a permanent increase in flaccid penis size of 1.7 centimeters (0.66 of an inch), and a permanent increase in erect size of the same increase (1.7 centimeters or 0.66 of an inch).

Interesting thing was the glans (penis head) showed a slight increase in size, as well.

A 2009 study published in the British Journal of Urology had similar findings, only with a larger flaccid gain of nearly an inch at the end of the study period.

The results of these studies show that the enlargement of the penis is possible, but in my option, due to the results after so much hard work, I find extension devices to be a terrible penis enlargement method.

Half an inch in all those hours of work? Not worth it…

With manual stretches, you can add more force to the tunica and ligaments, and pull in different directions, which is very important. Also, jelqing and other exercises work to increase girth as well, and extension / traction devices lack in that area.

Study On Heat And Elongation Of Collagenous Tissue

study on penis enlargement exercises e1443725315462 300x275 Science Supporting Natural Penis Enlargement   Studies, etc.While not a penis, this study shows some interesting effect on how heat, and applying force, leads to permanent elongation of collagenous tissue (using rat tails as the tissue). Our penis is made up of collagenous tissue.

From the study:

“The data showed that the low force, long duration procedure was very effective at producing residual elongation. Elevating tissue temperature and maintaining it prior to applying force was found to cause significantly less damage; and finally, the lower loads applied at elevated temperatures for prolonged periods were found to produce significantly greater residual elongation.”

Before you freak out at the word damage, just know, when you are lifting weights, you are “damaging” your muscles, and they heal in a larger state.

While the mechanism in enlarging penis tissue is slightly different, it does involve a “breaking” down of the tissue at a micro level (painless /actually feels good), and as the survey showed (and I’ve personally seen), penis enlargement techniques greatly improve erectile duration and hardness.

This also shows the importance of warming up before (and during) your penis enlargement exercises… it’s not just for injury prevention, but actually leads to greater gains.

Photo Evidence That Natural Penis Enlargement Works

One of the strongest pieces of evidence for me are before-and-after photos showing the results men have gained with penis enlargement.

Anecdotal evidence is one thing… scientific findings in a controlled setting, without visual evidence, can be questioned, based on the motive of the group conducting the study.

But SEEING, with your own eyes, a penis that has been enlarged, is powerful proof that penis enlargement works.

And I’m not talking about a half inch gain here… I’m talking about some pretty serious gains, both in length and girth.

Men who’ve read my guide have sent me before-and-after photos showing the gains they made, and I’ve collected them all on one .pdf file.

I won’t post them on my site, as having a bunch of penises on my site may confuse Google as to what my site is really about. To see these photos, shoot me an email to with “Photo Proof” in the subject line, and I’ll reply with the .pdf attached.


I know the scientific findings leave something to be desired.

There needs to be a larger scale study on penis enlargement methods in a controlled environment, by an unbiased, and highly reputable group.  Then things may change, doctors may begin recommending penis enlargement exercises, and the term “penis enlargement” will no longer have such a negative connotation.

As for now, while there is some scientific backing, penis enlargement requires a leap of faith more than anything. Warm up, don’t overdo it, and you won’t injure yourself… your penis is FAR more resilient than you think it is.

Once you see you are measurably larger, the doubt will be removed from your mind.

Replicate Your Girl’s Riding Movements When YOU’RE On Top

how to give a girl an orgasm during penetration e1443470696794 300x256 Replicate Your Girls Riding Movements When YOURE On TopWhen my girl rides herself off to a few orgasms on top of me, I find it interesting the manner in which she does it.

It’s a VERY RAPID rubbing of her clit back and forth while she’s on top.  She’s very quickly grinding, with the fury that only fighting after an orgasm will create in you.

But the thing is, while I can make my girl orgasm by rubbing against her clit with my pelvis during penetration, replicating the EXACT movement is not easy.

Especially as a man, especially when I’m on top, and especially because I have a penis inside of her.

But with that being said, making her orgasm during penetration, the same way she gets herself off, is possible. And I’ve mastered it.

She was asking ME to please not orgasm… to hold off… but I wasn’t even close. She was speaking for herself.

Yesterday, while I was on top, I went for an all-out replica of her riding motion.

I penetrated, but with a VERY fast up and down motion against her clit at the same time.  A hard, relentless, SWIFT grind. Speed seemed to be the key here.

It was tiring… that it was.

But it was effective.

Within two or three minutes, and I’m talking no foreplay, no eating her out beforehand, she asked me:

“Please babe, hold it… don’t finish yet…”

I wasn’t close… this was funny to me.

She was right there… and she loved.  So I continued the quick grind/rub/drill motion, and within a few more seconds her pussy was tightening up and vibrating on my penis in orgasm…

And I still wasn’t close.

A good position to last long during sex, and give her orgasms at the same time

Most of what is supplying the pleasure is the rubbing against her clit with my body.

My penis inside her prods, and feels good, but it’s not what is providing the real orgasmic stimulation.

Not to mention the way I was penetrating didn’t provide strong stimulation to my penis in the way that gets me off… That’s why this is a great position/penetration tactic for men with premature ejaculation.

She LOVED it… and didn’t want it to end

I wanted to finish in the doggystyle position (what an ass my girl has…), but she laid there like a spoiled child… “keep doing it, please…”

Orgasm after orgasm I was giving her… and when I’d get up and tell her to turn around… “just a couple more, babe…. please”.

So I pulled a fast one, and went for the ol’ “in-out, in-out” ramming that gets me off…. and got her off on one last powerful, simultaneous orgasm.

I now have new trick up my sleeve! Hopefully you can use this, too!

Your lady is your best teacher

 Replicate Your Girls Riding Movements When YOURE On TopWomen usually know how to get themselves off…

I remember when I was younger, I had the dumb egotistical need to be the “orgasm giver”, so if a woman would ask to get herself off by riding me, it bothered me (I know… stupid).

And back then, a lack of understanding of the female orgasm, combined with premature ejaculation, ensured that I was never the “orgasm giver”…

In time I gained ejaculation control, and learned more about the clitoris, g-spot, and cul-de-sac, so I was giving women orgasms with me on top… but there’s always something to learn from the girl herself.

How are we going to know more about what they like than them?

One girl told me for her, she felt her g-spot was in her ass… so guess what, I put her on all fours, and she was having explosive anal orgasms, with very little work needed on my end.

Another told me she loved oral sex more than anything… so guess what, her legs were on my shoulders, and my tongue was sliding up her clit. And she was quickly getting what she like’d.

Ask them… and listen!

And when they ride you, watch!

And replicate!

Also, find out what she DOESN’T like…

My current girl HATES when I suck on her earlobes… something a previous girlfriend used to love (I for one hate a woman slurping on my ear… so I can understand her).

I had a previous girlfriend who HATED oral sex as well… her orgasms HAD to be with a penis.  (Men with premature ejaculation are shit out of luck with that one…)

Just ask her… finding out this info means you are intelligent… not ignorant.

Let her guide you… it doesn’t make you weak… then before long, you’ll be taking charge!

If you’d like further guidance on how to last long during sex and give women powerful orgasms during penetration

Premature ejaculation was something that plagued me for a long time… it felt like a hopeless task, trying to overcome it.  Luckily, I’ve found some techniques and exercises that have actually helped me learn to last as long as I want during sex… for more on these techniques, click here…

And while being able to delay ejaculation is important, you don’t need to be able to last 20 minutes to get a woman off.

As mentioned above, I get my girl off in under 5 minutes, and I’ve done this with several women, for a number of years back now.  So it’s not a fluke.

Clitoral orgasms, squirting g-spot orgasms, deep end/cul-de-sac orgasms, anal orgasms… making her cum with your mouth, fingers, and dick. For everything I’ve learned about the female orgasm, click here…

All of this information can be found, in my guide, Mr. Manpower’s Guide. Any questions, shoot them over!

Have a good one!!

Psychological ED Plays A Role, EVEN IN Physical Cases Of ED

how to overcome psychological erectile dysfunction1 300x300 Psychological ED Plays A Role, EVEN IN Physical Cases Of EDI recently read an article on erectile dysfunction where they mentioned that young men are experiencing ED, and for physical reasons, NOT psychological reasons, like previously thought.

Most sources also mention how men older men have ED, but for physical reasons…

As if they are mutually exclusive….

Even young men, suffering from a psychological block to get an erection, can improve physical factors, in order to get their erections back. Just like older men, suffering from physical ailments can greatly benefit from “removing” any psychological mental blocks to getting an erection.

Physical and psychological ED ARE NOT mutually exclusive, and as a matter of fact, one almost always plays a role in the other.

How Psychological ED Factors Into Physical ED, and How It Makes The Situation Far Worse

In many cases, if a man — with a physical ED-causing condition such as diabetes, high BP, prostate issues —  were to have a calm mind/blank slate, and just allow arousal to naturally grow, he can still achieve a rock hard erection… it may take some more time than a young man, and some more stimulation, but with enough mental stimulation, he’ll be able to get it up…

But throw in the negative mixture of anxiety and fear over the situation that creates this mental block, and you have an erection that’s not going anywhere…

If a 19 year old male, with testosterone levels through the roof, and perfect physical condition, can go through LONG time periods where he can’t get an erection due to psychological reasons, imagine an older man who actually has a physical “excuses”?

Right from the start he’s thinking:

  • “I can’t get hard… it’s normal for a 50 year old to have weak erections…”
  • “I can’t get an erection… it’s the blood pressure meds… I will need Viagra”
  • “I have diabetes… men have erection problems when they have diabetes”

When in reality, if he just accepted “yes, I’m older, but my erection WILL work”, and was just patient with himself…. and ENJOYED the sex fully, without any cloudy, negative thinking and anxiety getting in the way, then he should be able to achieve a full erection.

A little more stimulation will be required before and during the erection, but if his mind stays sufficiently aroused, he will be able to stay harder longer than if it were racked with worry.

Physical Factors DEFINITELY Do Play a Factor in ED, Though…

how to achieve stronger erections e1443198913912 300x298 Psychological ED Plays A Role, EVEN IN Physical Cases Of EDImagine your mind state as the gatekeeper between your arousal and your erection.

Get your mind in the right place, and the arousal “energy” flows…

That is a PREREQUISITE to getting an erection on command, when you need it.

HOWEVER, regardless of the importance of your mind state in getting it up, physical factors do, without a doubt, play a major role in erection quality!

Take a man who just had a prostatectomy for instance…

While surgery has greatly advanced to the point where they can remove the prostate, without harming any major neighboring areas that help in the erectile process, it is quite common for men to suffer some “downtime” after the surgery, during the healing process. Once a day Cialis can greatly help with this process.

And men suffering from extreme diabetes for instance… if their circulation is extremely impaired, medical treatment may be necessary…

But doesn’t mean physical factors can’t be improved, or reversed altogether…

Improving the Physical Condition, To Support The Arousal

In men of ANY age, even very young men, there are things that can be done to improve the physical condition.

Aerobic Activity

If you don’t move your body on a regular basis, and live a sedentary lifestyle… then you will have a lifeless and sedentary dick as well!  Get up and go for a run… and on a regular basis! Get that blood pumping and flowing through your body… let it reach your genitals, so that your penis will come to life when required!

Upping Your Vitamin D

A large percentage of the male population is not getting sufficient Vitamin D, and Vitamin D is vital to testosterone production.  Do you drink milk on a regular basis?  Take a multivitamin?  Get sunlight on a regular basis?… if you don’t recall doing any of these, then you should start!

Trimming Some Stomach Fat

Stomach fat and testosterone have a strong negative correlation.  Being a man with a slightly growing gut myself, I know it’s hard to control this, but trim stomach fat where you can, and you reduce the amount of oestradiol (a form of testosterone-killing estrogen), floating around your bloodstream… this goes hand-in-hand with the cardio tip.

Keep Your Cell Phone Out Of Your Pocket

I once had an older Chinese woman tell me to keep my cell phone out of my pocket if I ever want to have kids… I thought she was ignorant. But she was onto something! A study published in the Central European Journal of Urology found that men who carried switched on cell phones for more hours of the day suffered from worse sexual functioning… whenever I have the opportunity, I keep my cell phone away from me.  If I’m sitting down, I put it on the counter next to my keys… but as often as possible, I keep some distance from it and my nuts!

These are just a couple of things you can do to improve your physical condition, allowing you to achieve harder, longer lasting erections.

For an advanced guide to strengthening the erection itself, making it physically harder, longer-lasting, and quicker to react, take a look at these exercises / techniques.

Overcoming Psychological Erectile Dysfunction Greatly Improves The Outcome

Once you have your physical conditioning down, you’ll be in a better place.  Remove any sexual anxiety, and you have a better chance of getting your erections back to full speed.

Overcoming psychological ED is more of a negotiation than a battle… it’s not about “acting confident”… because you will just be acting, when deep down you are anxious… causing a separation of mind and body.

Admit you are anxious. It’s okay. You’re human.

All of us get anxious before sex; we even experience anxiety with long-term partners, especially if we haven’t had sex in a while.

Admit your anxiety, and it will be easier to see and work with, and will weaken it’s power at the same time.

Why You Can’t Last Long During Sex With Someone New

cant last long during sex 300x240 Why You Cant Last Long During Sex With Someone NewUnless you’ve knocked down the perfect amount of shots to delay ejaculation, without suffering whiskey dick, most men can’t last long during sex on a first time encounter with a new chick…

And it’s not that you’re necessarily a born premature ejaculator… let her know there’s a biological reason behind this:

Your swimmers JUST CANNOT WAIT to get out and meet her…

Apparently this goes back to caveman days, when competition with other cavemen to procreate, and the risk of being gored by a woolly mammoth in the midst of fucking, created the need for men to get off QUICKLY.

Also, due to the difficulties of pregnancy, and chances of losing offspring early, men needed knock up as many different women as possible… our swimmers just want something new!!

Not only do you ejaculate faster when presented with a new woman, but you ejaculate larger loads, and with more mobile swimmers in your load, according to a Wooster College study…

There was no need to last long during sex in the caveman days… but damn it, things have changed!

Now we’re supposed to be able to last long during sex… men are supposed to be these amazing lovers…

Add to this that many women will give us one chance to impress them in bed, especially if they are very attractive, and have many men vying for their attention.. With their head blown up because of these reasons, many women will cut you loose after one bad sexual experience (shiettt… I had it happen to me!)

And with women wanting us to last 23 minutes on average, according to a recent study in Journal of Sexual Medicine, our caveman-trained sperm is selling us out.


Good news is, as long as your sperm gets used to (bored of?) your girl, you should be able to last longer during sex… but these tips will help you for the first time:

My intro was not a joke… if you want to last long the first time, take a couple of swigs of something nice and strong, but don’t over do it… this will numb your penis and sensations, allowing you to have better ejaculation control, and better impress your lady friend.

Forming a better, deeper connection with her OUTSIDE of the bedroom will give you a better chance of getting a round 2 with her, whether on that same day, or on a later date… not all women are so judgemental that you won’t get another shot (also, premature ejaculation is quite common in men, so more than likely you won’t be the first one to have blown a quick load with her).

Something else that helps is to get her off orally/manually first before entering to penetrate.

Not only will you ensure that she’s had an orgasm during your first encounter, but you will take some of the pressure off to last long during actual intercourse, which may actually help you last longer… but your wiley sperm may have something else in mind.

Round two will be better… just let her know…

Now, if you have problems lasting long in bed while in a regular, long-term relationship, then you may need some extra help. Ejaculation control exercises and knowledge can train you to last much longer… click here for more in-depth ejaculation control techniques.

Have a good one!
