I am a 25 year old man and I have been masturbating since 14. I know for a fact that it has caused me to have erectile dysfunction. When I am with a girl, I get a soft or weak erection and it is very embarrasing to say the least. I have quit masturbating for a week now, but nothing feels any different. Does anyone know exactly how long I will have to go w/o masturbation to get back to normal?
