um, what?
Anyway, there aren't really any disadvantages to masturbation. Except that you may condition yourself to only orgasm during masturbation, or on the other side of the the coin, gain stamina through masturbation (can masturbate for significantly longer before orgasm) but suffer during actual intercourse.
If you do it regularly it isn't a big deal. If you do it *a lot* then you have more of a chance of having the problems stated above. Either way, the chances are probably pretty low.

excess of everything is bad if u rub penis or vigina too much it will harm it bit but wot I say dont rub it too much in masturbate people even after orgasm rub there organ too much. Wen u orgasm then stop becas u hav relaxed ur self. Oh u said masterbate can increase or gain stamina I say may be not becase over masterbation lessen ur sex power. I dont say dont masterbate its bit natural for every energatic youg to hav fun but use gentle way becas skin of penis & vigina both r very sensitive. I can say confidently about penis but about viginia girl can comment well. Penis if jacked off frequently mean rubed too much its skin get irritated & rough and its effect blood pump & erection. Wot is best for penis is get arous by watching sex movies seen prons by blow job by rubing it between thigh like this which doesn't effect much on skin. So sam for vigina I think hard thing will effect like hard dildos vegetables etc so why not see movies see prons talk sex use light ways. My question here is wot a girl can do to kill her desire and at same tim dont hurt vigina.

r u male or female? If u dont masterbate its good it will have no effect try not to involve in this
