I read somewhere that if you overmasturbate you could have health problems and stuff, but how do you know youre overmasturbating? when is it too much, like everyday, or every other day, or how often?
It's nearly impossible to masturbate too much. Some people masturbate 5 or 7 times a day, some people once a month or less. Both are within the realm of "normal" (though at the outer reaches.) A lot of people in their teens and 20s masturbate 2 or 3 times a day; that's very common. The only concern is if you start getting physically sore or sensitive (from too much rubbing). Then maybe it's time to back off a little bit. Otherwise, nothing to worry about.
Masturbation is no different than any other sexual activity. If masturbation really caused things like blindness, every good looking bastard in the world would need a seeing-eye dog.
Two main signs you're doing it too much. 1. If you're experiencing physical symptoms. If your penis is very tender from over-stimulation, or if you rub it to the point of getting a rash, you're doing it too much. If you do it so often that it takes you a LOT of time and effort to reach orgasm (and the orgasms aren't that amazing), then you can probably lay off a bit. 2. If you're experiencing social symptoms. If your schoolwork is suffering, if you're ditching your friends to stay home and masturbate, then you're probably doing it too much. Other than that, you're probably fine. Lex
^ that, basically. It's generally a good idea to semi-limit yourself to masturbating daily. I do that for the most part, and it's a good balance.
