I am forty years old. Married. Have two kids. One year back I got afflicted with
diabetes. For last six months or so I have observed that I don't get long lasting erection. Even if I get it is after much stimulation. I am not able to enjoy sex with my partner. I want to know, am I heading towards impotency. I am a complete teetotaler. Excercise regularly. Is this normal or I need to consult doctor. Please suggest.
