I got fingered more rough than usual 2 days ago and more fingers were used, and we attempted sex (my boyfriend and I), the next day my vagina was a little sore, and then it got a lot worse after I masturbated, since last night it has been terribly itchy and painful, this seems to mostly be coming from inside the vagina, and he was wearing a condom. He barely penetrated me either. Could this be from too much rough stuff in 1 day? Do I have an infection? Will this go away? I'm using sudacreme do smooth the burning sensation, will this help?
