I am a 32 year old, circumcised male. When I was 28, I was taking an asthma medication called primatene. I tried to masturbate later that night. I noticed it was difficult to maintain an erection. The orgasm was dull and sensation-less. Ever since then, I have had dull orgasms with little feeling. I have difficulty getting and maintaining erections. On dates, my penis leaks out what I assume is pre-ejaculate in larger quantities than is normal. I can still have an erection, but there is really no point. I don't enjoy it, orgasm has little feeling. It lacks that tight feeling I used to get. I get a similar, but painful version of the tight feeling sometimes after the gym and preworkout, so I assume it has something to do with NO3, but it just feels like something is broken. I do not know if there is internal scarring, or if something has been stretched out, but something is seriously wrong. I have gone completely abstinent in hopes that if I just stop messing with it, and if I cut out sexual stimulation, something can be fixed. If you can help me, I would be delighted. My physician told me not to worry about it a few years back, but I think that was bad advice. I have recently met a wonderful woman, and I want to marry her. I would like to at least have some hope that I can get back to an enjoyable sex life. Thank You.
