It is especially good for relieving stress caused by schoolwork, by sports, by problems at home, or by peer pressure. The human body constantly makes more sperm all throughout a person's life. Also, for girls, masturbation has no effect on how many eggs are inside of their body. Putting sperm on a girl's breasts does not make them grow. It also has nothing to do with whether they are gay or straight .
Some people masturbate while they are sleeping.
It is even possible to have an orgasm during sleep, and it may or may not be remembered the next morning. While sleeping, it is common for the penis to become erect and for some of the seminal fluid and sperm to be released onto the sheets of the bed. Erections are normal in boys and men of ALL ages and usually means that he is sexually excited or aroused. It can also be a reaction to being accidentally touched or bumped or rubbed, and sometimes they happen for no apparent reason at all. For most guys, having an erection in front of anyone but your lover is very embarrassing, but it doesn't have to be if everyone understands that sometimes they just happen and that there is nothing wrong about having an erection.
