I have seen many people complain of the complete opposite problem I have. Many people are concerned that excessive masturbation causes weaker erections, but I find if I do not masturbate for a few days, it is impossible to get a hard erection. However, if masturbate with this weak erection 1 or 2 times within a few hours, then I can get hard erections at will until I stop masturbating again. Does any one else have this problem?
Just sounds like you're more aroused after masturbation, I don't consider that a problem. By touching and giving your penis attention, it responds by being easily aroused.
