Hi yall,I'm in need of desperate help!three weeks ago I had an unprotected sexual encounter with a guy I had considered to be a potential boyfriend,bt it was only for 2secnds because of the surroundings.and a week ago my real boyfriend which we had broken up at that time came back nd we reconciled and ddnt use any protection.the day after we had sex I had an itchy feeling around my vaginal inside nd clitoris,bt nothing visible came out.after two to three days it was painful when I urinated,nd inside the lips of my vagina(lubia)I had scarring as if I poked myself with a sharp object .it doesn't look like a pimple nor swollen but round with red trimming nd white inside and it hurts and buns like hell!!when I put on vicks vapor rub and it eases the pain and the itchy-ness.pls plz help in advising seeing as I'm confused whether its sexually transmitted or what..
