Vaginal Sore

I noticed this sore on my vagina maybe a couple of months ago. At first I thought maybe I knicked myself while shaving because i had noticed it right after shaving and noticed it was bleeding when i wiped after peeing. it stuck around a little while but eventually seemed to go away until tonight i noticed it again. Same spot, same sore. I don't know what it is. Hurts if i mess with it like when wiping or bathing then it gets irritated and sometimes bleeds. posting a photo. Sorry its not great but best i could get.
