January 1, 2010, I had protected anal intercourse with a girl i didn't know and while having intercourse the condom broke. I didn't know it broke so i probably had intercourse for 5-10 minutes and immediately washed my penis. I didn't experience any HIV or STD symptoms. I had a skin irritation below my belly button that eventually went away after applying Lotrimin. First week February I started to date my girlfriend and we got tested. She tested for everything (negative results) and I only tested for HIV at same day results clinic (negative results). I never experienced any STD symptoms. Last week I felt a tingling feeling on my pubic hairs and I cut them off. The tingling feeling is mild around my scrotum and on my buttocks and thighs. I also have two painless blemishes on my penis. I don’t have any pain during urination, no other pee colors, no sores, no lower back pain, no headaches, no pimples, no blisters, no painful intercourse, no rashes, no warts (not sure if blemishes are warts, look nothing similar to pics online) no itching. What has me worried are the blemishes on my penis. One resembles a flat scab and the other is small spot. I have been having a constant tingle in my genital area. When sitting down, I experience a tingle I can re-adjust my penis and it stops but the tingle can persist on the side of my thigh, buttocks or scrotum and seldom on my penis. I experience no tingle walking, working out or during sports. My scrotum had felt tender for a few days but I had worked out and had soreness from working out in thighs but discomfort has decreased, as my body has recovered from workouts. I had sex with the unknown girl Jan 1 and it is November. Is it possible to start experiencing STD symptoms 11 months later? If i had an HIV test wouldn't that have detected an STD? Could the blemishes on my penis be genital warts? Could I have Herpes? Are STD's dormant like HIV? If i don't have an STD how can i stop this tingling feeling?
