About 27 days ago I had protected sex with a girl I knew from many years back. I believe I fingered her vaginally prior to putting on the condom but I’m not 100% sure. Immediate after the sex (which lasted 5-10 min) I cleaned my genitals with soap and water and even doused the area with rubbing alcohol because I know how paranoid I get. A few days after I had some intermittent itching and possibly some random burning at different locations in my pubic area. I convinced myself that it was probably just from recently clipping/shaving my pubic hair...which only worked with my mind for a bit. A couple weeks after I got what seemed to be a cold/allergies: didn’t feel bad but I had congestion, drainage, sore/swollen lymph nodes in neck but all has since gone away. Here within the last couple weeks I have gas-like pains that come and go and will sometimes radiate from abdomen (appendix and/or behind bellybutton area) to my testicle(s). These are not painful but discomforting especially because it adds to my stress and paranoia. The last two days I seem to be urinating more frequently although not intaking more fluids than normal (might be mental but I noticed it today). No pain when I pee, no discharge, and no fowl smell. I have read way too many std/sti articles this last month and I would like some advice for my symptoms specifically. Thanks in advance.
