"Common concerns about masturbation include whether it causes impotence , premature ejaculation, infertility, shortening of penis, reduced testes size, penile curvature, difficulty with intercourse, insanity .. and so on.
Contrary to 流行的 belief masturbation DOES NOT cause any of them. On the other hand, it could be utilized as a learning tool towards reaping a greater sexual pleasure, overcoming premature ejaculation, becoming orgasmic and so on.
As to premature ejaculation I have to say a few things. Yes, masturbation CAN lead to premature ejaculation , but it should be understood that it's not the masturbation that is at the root of the problem, but the way one learns to masturbate.
Many people, in course of their masturbatory experience, have learnt to masturbate to rapid orgasms. For example, many people want to do it fast and get over with it as soon as possible so that they have fewer chances of being detected. In contrast, those who have learnt to be slow, spend good amount of time stimulating themselves on and off several times before ejaculating, have evolved to gain control over ejaculation even during sexual intercourse."
