I have just started having intercourse with a new person last month. But I did it unprotected. Now I've noticed that my vagina is producing alot of discharge. It's yellow and it smells bad also. Also by rectum it feels as if its raw. It burns. And Ive noticed that I'm itching alot down there also. Before I had intercourse with him, my doctor told me that I didnt have any diseases down there. So what does this typically mean?
