I am 22, male and have had intercourse with 62 woman (do not mean to show off) and have never had any problems with erections, until 4 months ago... I use to have a perhaps over active sexual drive... It was not uncommon that after the first orgasm I stay very hard and continue .... Now all of this has changed and I haven't found any sollution to my problem... My doctor said I must be fed up of sex and that after a period of time it will go away... Well 4 months is not little... In this time period I have had only three sexual partners which were not happy with the sexual experience I offered because the erection if any was very weak... I haven't managed to sustain any of the relationships... Only way to have a so to say 70% erection is to masturbate... apart from that I don't get erections, not even when I wake up in the morning or get in close contact with woman... Any advice is highly appreciated...
