I'm 41, in reasonable shape (slim) and started experiencing a decline in my sexuality over the past year or so; difficulty with erections, no spontaneous erections, low interest in sex, constant stimulation required to maintain an erection. I've been single for approximately two years and recently started seeing a very beautiful woman. Well, lo and behold, the ugly issue is raising it's head (no pun)and my anxiety is through the roof! I've always been highly sexual and had no problem with three or four orgasms a day. I started masturbating in my early childhood and became sexually active around age 13. I've always used porn and have engaged in long edging sessions with no apparent issues getting hard as a result. I'm usually a little soft with a new partner until I can feel a sense of security and trust, then I'm off to the races. Now I'm dead in the water. I can get hard with my new girl, but it only lasts a short time before disappearing. Sometimes, I feel no sexual feelings with her at all, though I do enjoy the intimacy. Any opinions as to whether long-term edging/masturbation can cause ED? Heavy porn use? I also quit smoking after about 20 years two weeks ago, so I'm wondering if that may be it? I did go to the urologist a few years back with concerns about waning libido, and he ran a blood panel. At that time he said everything looking normal with my testosterone and gave me vitamin V which I hate to take. Again, I went to a GP about 9 months ago for a physical and he also did a blood panel that came up normal. As far as meds, I've been on and off of Wellbutrin XL for 4 or 5 years. I recently started taking it again within the year. Several Doctors have reassured me that the XL has no sexual side effects, but I'm skeptical of that as well. Also, to clarify, its not as if I'm horny and simply not getting blood to my cock. Its more like I have to force my attention to sex to see what's up- as if my sex switch has been flipped in my head. Then the anxiety comes if nothing starts happening. I know this post is all over the place, but any input would help.
