my boyfriend and I have been dating for five months. Yeah sure we fool around. Well one night, he is fingering my vagina and he accidently cuts the outside with his nail. Day later I started my period. This wasn't an issue until a few days ago when I was changing a tampon and the place here he cut me started stinging really bad. I necked it out and even showed my mom. There is a cut with little bumps around it. It itches so badly. Well yesterday, I scratched it and found a new cut out of nowhere. I don't know what to do. Is this more serious than a simple cut from a fingernail? We haven't had sex so it couldn't possibly be an STD. HELP!!!!
