You cannot diagnose STD through your masturbation habit or masturbation problems. In fact, masturbation is a normal and natural method and is never unhealthy if your masturbation is within limit. You may masturbate thrice a week to be physically and mentally healthy. Difficulty in ejaculation during masturbation could be due to lack of commitment passion or masturbating without desire. I suggest counseling to you. If you require more of my help in this aspect, please use this URL. Make sure that you include every minute details possible. Hope this answers your query.
