I am 62 years of age. Six feet one inch and 168 pounds. I am married and have been for 35 years. The marriage is very affectionate but largely sexless. I am unable to maintain an erection with my wife. Two years ago, much to my regret, I got into another relationship that ended 6 months ago. We never had penetrative sex, she gave me oral sex. I half entered her just once, and then for a couple of minutes only before discontinuing. I have been checked out for 'standard' STIs - chlamydia, gonnorrhea, syphilis, HIV, and shown clear. This was after I started to worry about having contracted something. I had some urinary difficulties that my GP felt were probably a UTI, and I was treated with Cipro. The current difficulty is that I started to focus on my penile area when I first began to sorry about it. Since then, I have noticed an almost constant tingling/burning in my penis (this has been over a period of probably 6-8 weeks. It seems to affect the end of the penis and the underside. There are no lesions.sores to be seen. It seems not to be there when I wake up, but worsens as the day goes on. I also seem to feel a tingling in the sole of my left foot. I suspect if may be psychosomatic, as it seemed to coincide with me first worrying about an STI. It also seems to be absent when I am distracted. My concern is whether there could be a clinical reason
