my boyfriend was fingering me and it was really painful and i didnt know why , and the next day i realized i have a cut on the lower part of my vagina( below my whole area) and its a deeper but small cut, and it doesnt look infected or anything , it just stings when i pee. Ive never had one before and i dont know how to treat it ? if anyone could give me some adivce thatd be much apperciated thanks.
