Hey all. So I have a irritation on the top of my penis. I got a handjob from a chick I met at the bar about a week ago. She also gave me head once and a while but not often. I went to the std clinic yesterday and got a swab done( not as bad as people make it sound). The swab came back negative for any bacteria. My question is what else could it be?? I don't have any other symptoms ( dicharge, burning pee, itch, rash, bump, cuts,). The irritation is not always there. I seem to get relief when I pull my boxers away or not where any. Its really freaking me out and putting my anxiety through the roof causing panic attacks. I should also mention that I feel a small pressure in my lower abdomen. I am a 28 year old male. Thanks much.
