hello . for the past two or three days , my vaginal hole (the one i have sex with) has been having a little burning sensation . when I have sex, it gave off a foul smell. after sex, my discharge is pinkish. I thought it was because my boyfriend is rough during sex, but it still hurts now. the discharge is now white again, but still has a smell to it. to relieve the pain, i rest my finger on top of the whole. i don t feel any type of bumps. also, for the past couple of weeks i haven t been using underwear with clothes (jeans, leggings). I don t know if that could contribute to it. please help me
