When masturbation is not OK?
Masturbation is not OK if it is the only source of sexual pleasure. In most of these cases, masturbation is only a symptom and not the reason why adult person can not have normal sexual relationship with the partner. The very reasons can be hidden in simple physical imperfections like small penis size, obesity, sexual problems like sexual dysfunction, insecureness, latent homosexualism and plenty of factors with psychological background.
