I have received oral sex in a darkroom from a guy that had blown another guy a couple of seconds before blowing me. The guy came in to his mouth an then he started to blow me. After a week or so, I had a fever for a couple of days and burning sensation while urinating (that started before I engaged in unprotected blow). Anyway, the burning sensation and fever have stopped, but I have had diarrhea for the past two weeks after almost every meal. I also have a burning sensation on the skin of the abdomen and on thighs. It also seems that my groin lymph nodes are a bit swollen. My doctor says it is just a stomach flu, but I am really worried. The encounter happened on the 1st of January. Is it too early to get tested for hiv? What are the chances of getting it this way? I am really nervous and I really don't know what to do. Thank you in advance!
