Doc, I had sex with a condom of course on Monday evening, there was anal sex invloved as well. This sexual experience is with a female, I am a straight guy, no drug use or anything like that. I had a condon through out the entire sexual experience. Afterwards I also then masterbated, hours later. The next morning my penis was soar & red. The head of the penis was bright red & red around the opening, when I walk it hurt some. When I urinate I think it stings a little, but it may be in my mind that I am focusing on it. I am not sure if I acquired a STD that quickly, the monring after, actually only hours later this all happened. Could be irritation. What do you think? I had NGU a while back but took my week's supply of Doxy, could the irritation cause that to come back? Or could this be a simple case of a irritated penis? The condom I used was lubricated but without spermicide 9. I also did not receive oral sex but gave oral sex, not long though. The weird part is the irritated opening to my penis, but how can that be irritated when I had a condom covering that entire area? Thanks my friend.
