Absolutely false! It is true that if you're highly aroused, your testicles become engorged with blood and may appear slightly larger and heavier, and that masturbating will make them revert to normal. But they will absolutely not be any smaller than after the last time you masturbated.
Chances are, of all the things you've heard about masturbation, most of them were absolutely false. For some reason, misinformation surrounds masturbation like virtually no other topic. Since JackinWorld's goal is to debunk misinformation, here are some of the myths commonly believed about masturbation – and the truth about each.
How do you spot a masturbation myth? One simple method is to ask yourself if the statement is also true of sexual intercourse. When you're masturbating, your body only knows it's getting sexually stimulated; it doesn't know by what means. So, for instance, if the question is whether or not masturbation causes acne, think of it this way: If it did, intercourse would also cause acne. In fact, neither masturbation nor intercourse cause acne.
It doesn't cause acne. Like the eyesight myth, this is a case of two things that happen at the same time, even though one doesn't cause the other.
Absolutely false!
Hello? "Sexually transmitted" means from one person to another. You can't give yourself a sexually transmitted disease!
Semen is a fully renewable resource. When you ejaculate semen, your body simply makes more – the same way your body makes more saliva after you spit.
Masturbation does not change the appearance of your penis. (It does tend to cause an erection, but that usually goes away when you're finished.)
