I believe that this is true for some men. I have never had occasion to know if it would be true for me.
This is a Staff Report and not prepared by Cecil himself. Please see the note at the bottom which I reproduce below:
All that being said, you all seem to be doing a good job here so please carry on.
I have noticed this to be true.
I have not masturbated for over week and a couple of days ago I observed my penis had extended enough to make me look at it twice, then a third time, and even a fourth time to confirm what my eyes were seeing.
There is an area in the middle where the skin has little stretch marks, it appears, yet they have disappeared now because I am on a nutritional balancing program.
The OP mentions committing a crime due to pent-up hormones, and I believe there is a lot more truth to this statement than it would seem on the surface of the language. Consider that, when a man is pent-up and horny, he might flirt overly much, or he may lust after another woman who is not his spouse. If there is alcohol involved, he may even have sex which he would remind himself is against his ethical code while sober. I had sex which wasn’t intended while I was drunk because I was at a male bathhouse, and it destroyed my relationship.
Is it a “crime” in the eyes of the law? No, the law does not care about who we have sex with. But is it a crime in that you wish dearly afterward that you had kept your self-control? Is it a crime unto your spouse, whose trust is violated in you? Truly, the meaning of the word “crime” goes much deeper than the textbook definition of an act which will land you in jail…
I couldn’t read this zombie thread because my eyesight is failing.
I can’t believe this post didn’t unleash a barrage of cites disputing this statement.
ETA- Zombie porn!
Manifestly false statements often get a pass.
And I’ll be in my bunk.
Hmm… Sandpaper? Sounds interesting!
I don’t believe the assertion is that the chemicals pool in the genitals and then are drawn from the genitals as the body needs them. Rather, I believe the assertion is that frequent ejaculation means that the body will work harder to produce more semen, and in doing so draw upon the resources of the body. Since the dietary intake of said resources is limited, having a larger draw for the creation of semen to support a frequent ejaculation habit will reduce the resources for other needs.
At least, that is the most reasonable interpretation of the remarks presented. I make no claims as to the validity of that assertion.
And, of course, girls don’t fart either. 
You’re inclined to believe that your brain is full of semen?
You know, you might just be right about that…
One anecdote, especially one in which you did not even measure, proves nothing.
What in the sam hill is a “nutritional balancing program”
Here in Philadelphia, you can find two kinds of bath houses.
The first is intended as a throwback to the old country. There you can find plenty of European immigrants and engage in male bonding. If the management finds you having sex in one of these, they’ll throw you out.
The second is a place for men to have sex with other men.
If you were in the first kind, I find it unlikely you had sex there. If you were in the second kind, I find it unlikely you went there for reasons other than having sex with a man.
Sure it does. You cannot have sex with somebody under the age of consent. That would be a crime. You cannot have sex with somebody without their consent. That would be a crime. You cannot pay somebody for sex. That would be a crime. You cannot have sex with a corpse, an animal, or a bunch of other things. There are plenty of laws regulating sex.
That word, I do not think it means what you think it means.
There are other words to express what you are saying, without distorting the language.
Call it a “mistake”, call it a “lapse in judgement”, call it an “abuse of trust”, call it a “regrettable act”, call it a “shameful situation”, call it a “sin” if you must. But reserve “crime” for things that are actually against the law. Otherwise you are impeding communication.
I-I first became aware of it, Mandrake, during the physical act of love…Yes, a profound sense of fatigue, a feeling of emptiness followed. Luckily I-I was able to interpret these feelings correctly. Loss of essence. I can assure you it has not recurred, Mandrake. Women, er, women sense my power, and they seek the life essence. I do not avoid women, Mandrake. But I do deny them my essence.
The problem is knowing which is which.
I read in a local newspaper yesterday that a janitor had found a used condom by the pool at an indoors bath, which led them to conclude that someone had rented the place to organise swingers’ parties. Interestingly enough the only public bath I know of in that area of town is at the police headquarters.
All right, folks, it’s time to stop playing around. All we’ve had in this thread is a bunch of Dopers tossing off anecdotal evidence and jacked-up cites. We need a group of volunteers with a hands-on attitude to generate some hard data and help us get a grip on the situation. I know the brave men and women of SDMB will rise to the circumstances and, seeing ignorance abroad, rub it out. Let’s get our hands dirty, Dopers; this research could be seminal!
Just strip down and ask!
10/10. Bravo!
