I made a mistake, I drank too much at a party and had sex with someone I don't know. The sad thing is I was a virgin before this. Luckily there was protection. I was so scared that I might have co reacted an std. 15 days after exposure I tested negative for Chlymidiah, gonoria, syphilis, and hiv. I was seriously nervous about herpes type II. I got tested and the same time, 15 days, results came back negative. No signs or symptoms. It is day 20 after exposure and I'm experiencing a little redness and irritation around my scrotum, inner thigh, and side of my penis. I don't see any bumps or sores. Could it still be herpes? Do I need to get tested again? I have been wiping my genital region with alcohol swabs and lotion. I have also been taking lysine as a precaution every day. Should I stop worrying and stop taking the lysine? What should I do? Am I over thinking it?
