Hiya ok so basically me and my boyfriend have been having sex for about a year, we were both virgins but we still use condoms just to be safe. The last time we had sex was about for days ago and since then I've noticed a sore spot right at the base of my vagina just on the area between my vagina and anus. Any ideas what this might be? It seems to be more of a sore flap of skin than a spot or bump.
