i am not a doctor but don't worry if you moderate in everything never will be bad for you and may even be healthy for you.its like asking eating too much food or not. of course everything if you do that to much is not healthy like eating food to much.but my advice is get a gf if you are guy and if a girl get a bf and have sex with her/him
goodluck my friend

is there any efect on kiddeny of masturbuating????
