Hi, I am a 55 year old healthy male. I have always been involved in sport and have always had an active sex life. My resting pulse rate is 51bpm, I ma not overweight and take part in rigorous exercise 2 to 3 times a week. I do not suffer from stress and yet have now started to suffer from erectile dysfunction. I have been a seeing nation health "nurse", not doctor or consultant, for 8 months now and we are no closer to resolving the problem. I have had all sorts of tests and told that I am normal for all except testosterone where I am high. I have been prescribed all sorts of tablets, pumps and now pellets I inject into my penis, however, although I will get an engorged penis, it goes bright red and swollen, it does not become erect. Incidentally, I struggle to masturbate. Because I cannot become erect, I have to hold and squeeze it really tight. This problem has been going on for a few years but because my wife lost interest in sex I just masturbated but as mentioned this became more difficult. I now have a new partner and cannot have sex.
