hello, me and my boyfriend just recently had unprotected sex like two days ago. and they day after that i was experiencing burning and itching in my vagina and its grown immensenlu irratating, there doesnt seem to be a problem with the look of my vagina but it just hurts, it even burns to pee, like im being shocked a lot. i talked to my boyfriend about this and he didnt have an answer except sometimes he gets little cuts on his penis while shaving as he did before we did it two days ago.. could this be the cause??
