For the past month, after my boyfriend and I have sex, i've been feeling severe burning pain. My discharge is normal, and it's not a yeast infection or anything like that, so i'm totally clueless. Also, the pain is on the outside. Just below the outer lips of my vagina, it gets red and raw, almost like it's stretching the skin too far and tearing it. Is that what's causing it? My boyfriend's penis is fairly large, and we normally have trouble getting it to fit. Is it tearing the skin on the outside? I'm totally clueless!
