For the last couple months I've had troubled finding out what's wrong. I had sex with this guy mostly three times a week nothing was wrong until one day I gave him head(with a condom on) and the back of my mouth got all red and itchy. A couple days later we were doing it and I couldn't keep going because it hurt, I went to a local clinic and the Dr. Said it was a yeast infection gave me some pills, but I noticed that my vagina opening was, well basically closed, I went to the hospital and the Dr. Said it was normal, but I know my vagina. It was not like that. What could be wrong....
