So last night i had protected sex with a guy, but unprotected oral. He came in my mouth. It was the first time, i didnt like it so i spit it out. After that i had a sore throat. But it seems like the soreness has gone away after i gargled some listerine... But now im feeling fatigue and i dont know if its related but i had like a bug bite on my wrist which had turned into like a rash with red dots but it isnt itchy. Im panicking if the red dots rash can be like some sort of std's or sti's. Ive had this red dots before but that turned out really bad that i was allergic to some medications i took for other reasons. Since then red dots rash has me freaking out.  Help!
