hmm, i didn't think very many girls do that, but i've never really asked any. guys on the other hand are far more likely to. but still 2 or 3 times a day seems like a lot. how do you have enough private time to do that? so i'd say 2-3 times a day is probably not normal for a girl, but i may be wrong. i don't think it is physically unhealthy as long as you don't do it in a way that causes harm to your body. but it can be psychologically addictive, maybe you have a slight addiction to sex. but most people do, at least a little. after you please yourself though, often times there can be an emotional let down(once the euphoria wears off), so it could effect the way you feel afterward. i think you are just at your reproductive prime, so you have a really strng urge for sex all the time. so you are pretty normal, just don't let it control your life in any way or make you feel depressed. as long as you don't have any moral convictions against it, like some people do, then you shouldn't feel weird about it. its definantly a lot more healthy than finding tons of sexual partners to satisfy yourself.
