So I recently shaved my pubic hair and I noticed a little red bump, nothing big or bad just small so I maybe thought an ingrown hair. I didn't think anything of it so I left it, we'll all day I would itch down there and then I realized the red spot opened. Later that night I had sex and during intercourse I noticed the red spot was still an open wound. So I kept going and we got done and i noticed some blood from her period because she just got off and some of it was on the wound so now the red spots are still here and there's tiny ones next to be big one and it opens from me itching it. What could this be? I don't think it's from the blood because we're both clean. Any feedback is nice
