Around Nov 2015 I had sex with a CSW. Received and gave unprotected oral. Received and gave protected anal (received for the first time so it was really painful, I'm worried that could affect the chance of transmission, although plenty of lube was used, no bleeding). A few weeks later I had a large red patch on my chest (can't remember exactly how long), it was not made up of little patches, it was literally just ONE large patch across my chest that did not itch. I thought absolutely nothing of it at the time and lasted maybe a month (I can't remember properly). I did not have any other symptoms. Then in April I came down with a really bad flu but no sore throat, but I think I caught this at work as something was going around. Being a paranoid person that I am, I had suddenly started getting scared and decided to get tested yesterday (I know I should have went sooner). I've been losing sleep the past few days. I'm basically just looking for reassurance because I've been stressed as hell.
