Question: Do Penis Pumps Permanently Enlarge Your Penis?


Thankfully, this question, which is one I received 43 times in my first year as a guide (not from the same person) is one of the easier sex questions to answer. And of course the answer is yes...and no.

Penis pumps will absolutely make your penis bigger, temporarily. Penis pumps create a vacuum effect that draws blood into the penis, which in most cases will result in an erection. Given that an erection is bigger than a flaccid penis, it’s true that penis pumps “make” the penis bigger. But only while they are on over the penis. And this can get in the way of things.

The only published study that has examined the effectiveness of penis pumps at permanent enlargement found the claims of thousands of ads, websites, and "real" guys who promise permanent size gains to be puffed up, just a lot of hot air.

The study was published in the British Journal of Urology International in 2006. In the study the researchers followed a group of men with small penises who were willing to use penis pumps three times a week, for twenty minutes each session, over a period of six months. The device that was used was not a sex shop style penis pump, it was a clinically tested vacuum erection device.

At the end of the study there was an average increase of 0.3 centimeters, which is not statistically significant. But interestingly, even though this average increase is minor, 30% of the men who participated said they were satisfied with the “treatment”.

Despite the fact that the actual gain was not significant, and for some participants presumably there was no actual increase, many of the participants felt satisfied, which makes one wonder what it was that they were satisfied with. Was it the permission to spend an hour each week focused on an activity that some men find pleasurable? Was there a placebo effect?

With only one published study, we would need much more to go on before concluding anything. Even so, I have always been wary of the penis pump sales pitch. In the end, as long as you use your penis pump safely there is no reason not to try it if you like, and there is no question that some guys say it makes a difference. But as far as the research is concerned, the difference is largely in their heads.

Pain During Intercourse

Experiencing pain during intercourse affects sexual performance as well as pleasure. It can even have lasting psychological effects such as fear of penetration leading to impotence. Not surprisingly, equating pain with intercourse can put a strain on relationships, so in this article I look at some of the physical causes of pain during intercourse.

Pain can arise because of infections such as herpes or sexually transmitted diseases such as untreated gonorrhea.

Foreskin Problems
An overtight foreskin (phimosis) or damage to the foreskin resulting from tearing, friction or inflammation can all lead to pain.

Deformities of the Penis
Conditions such as hypospadias or scar tissue from previous traumas or infections.

This is a condition where a non-sexual and often painful and sustained erection occurs.

Allergy to the penis by vaginal fluids or contraception chemicals.

Hypersensitivity of the penis
This can occur post orgasm and ejaculation. Growths (benign or cancerous), urinary tract stones or penile deformities.

Pain during intercourse is not normal and should be checked out by a medical practitioner. Do not continue attempting intercourse until you have recieved treatment. This is especially important if the cause of pain is due to infection.


Penis size is determined entirely by factors out of our control. Yet penis size may be the single greatest cause of anxiety for men young and old. Questions about penis size abound; What’s the average penis size? Can I increase my penis size? Does penis size matter as much as I think it does? Some of these questions have easy answers, most of them don’t.

What can safely be said is that concern about penis size is almost always misguided. Great sex is much more than the sum (or length) of its parts. Hopefully learning more about what researchers and regular folks have to say about penis size may help more men understand that.

Question: How Much Masturbation is Too Much Masturbation?

I need help. On your site it says that masturbation is great and healthy and everything, but then it also says that you can do it too much. But no one tells me how much masturbation is too much. Basically I do it at least once a day, mostly in bed, and sometimes more. I don’t have a girlfriend right now, and I don’t want to damage anything down there. Can you just tell me yes or no, is masturbating once a day too much?


I wish I could answer your question easily, but masturbation isn’t like eating right, the FDA doesn’t offer us a "daily allowance" for masturbation (which is a good thing too, because I’m sure they’d give us some low ball number). Masturbation, like all of sex, is related to many things, physical, emotional, psychological, social, spiritual…the list goes on. So there’s never one answer to the question how much masturbation is too much masturbation or what qualifies as over masturbation.

This isn’t to say that you won’t find people who will give you a simple answer to your complicated question. The question of how much masturbation is too much has been the focus of some people’s life’s work, dozens of books, and countless religious tracts and sermons. Some say masturbation is terrible, some say masturbation is okay, but only when you’re young and single, and some tell you the truth, which is that masturbation is perfectly healthy and an important part of sexual health. With all these conflicting messages what is most important is that you do exactly what you’re doing right now; ask the question for yourself.

Too much masturbation can’t be determined only from the number of times you’re masturbating in a day or week. You need to dig deeper, and you can start by asking yourself some other questions about your masturbation habits:

  • Is your masturbation causing you distress?
  • Is your masturbation causing (unwanted) physical pain or damage?
  • Is your masturbation getting in the way of your life in unwanted ways?
  • Do you find yourself literally unable to stop masturbating?

If you answered yes to any of these questions, then I would say it’s possible (but still not definite) that you are masturbating too much right now. This doesn’t mean that there aren’t other times in your life when masturbating everyday would be perfectly fine. It also doesn’t mean that there aren’t people out there who masturbate everyday (or more) and who are completely healthy and have no reason to masturbate less. Remember, there isn’t a magic number, and we all use sex differently.

If you do think you’re masturbating too much (that is if your masturbation is causing you distress, or pain, or it feels compulsive, or it’s getting in the way of your daily life) it may be something you want to talk to a professional about. Be sure it’s someone who is comfortable talking about sex and isn’t going to make you feel bad for your healthy sexual expression.
