I am a 25 year old man and always had sexual problems, visited doctor but no problems found.
The problem is: at the start of the sexual act, i have an erection and as soon as I start sex, after 2 min it falls down and I need around an hour to get him back to work.. After that, my sexual intercourse either continues for 40 min or my penis dies.. Rarely, but sometimes it all goes well, 10 min and done. Please advise what shall i do?
Thank you
