I gave and received unprotected oral to a guy who's STD status I do not know. I asked him several times and he insists he is clean, but anyway. I got strep throat a few days after the sexual encounter. I was on amoxicillin for it for about two weeks and I got a yeast infection as a result, I used equate 3 day antifungal suppository and for the most part my symptoms went away, but I was still stuck with this itch on my vuvla lips two weeks later. It only itches/feels uncomfortable really when I walk. Could this itching be a sign of an STD such as herpes genital warts etc. I had one pimple that was filled with pus that I squeezed and the pus came out followed by some blood that shout out onto my mirror, I put a warm towel on it for a while and when I woke up the next morning it was almost gone. I am about 260 pounds, so maybe it could be chafing from my thighs rubbing together?
