Hey, I had unprotected sex last week, and experienced no pain or problems after. On Monday I masturbated using a vibrator. Since Wednesday I have noticed sores around my vagina, they are almost like ulcers, not massively painful, or pus filled. But I am starting to freak out. I have a history of problems with thrush, and am wondering whether this could be a severe case of a yeast infection??? I have no other symptoms apart from the sores, and what I believe to be thrush. I know this guy has just come out of a relationship, as have I, but I also know it is possible to carry the virus. I am really freaking out, as I really like this guy and am praying its just a yeast infection. I know I should go to the doctors, but generally wanted some advice. PLEASE HELP.....
