I'm a fairly healthy 45 year old male who has been married for over 9 months. I've been masturbating for the last 30+ years of my life, on an almost daily basis, using mostly porn for viewing stimulation. My wife is very attractive and we have unprotected sex at least once per day, every day. And, I rarely, if ever, masturbate anymore. But, from the beginning, I've been having problems sustaining an erection and even worse, not ejaculating most of the times.
