I'm a college freshman. In high school I wasn't sexually active, so when I got here I was just curious. I know it was very stupid of me, but I downloaded Grindr and met up with a guy on September 24, 2017 at about 4 AM. I was unprotected and there was ejaculation inside of him. That night after it happened I went back to my room and cried. I thought my life was over. I messaged him again and I asked are you HIV positive and he said no he wasn't and that I'm freaking out for no reason, then he blocked me. I made a new account and asked again, he promised me he wasn't positive. On October 22, 2017 I noticed a bump on my arm that I scratched and within a few days, it spread around my arms, it was very itchy, I would sometimes wake up in the middle of the night just to scratch. I went to a doctor and he said it's most likely just an allergic reaction due to soap or laundry detergent since I change quite a bit. It is now December 11 and the rash is still basically there, just not as bad. I haven't had any other symptoms, which is why I would like some reassurance about this. I've read that the ARS rash does not itch and tends to disappear after 2-3 days. I'm scared to get tested and this anxiety is really killing me. It's getting in the way of my daily life. Any help is appreciated.
