It's the Itchy and Scratchy Show!

Well no, it's not really the Itchy and Scratchy Show, but my beautiful lady part sure is! It all started about a couple of weeks ago. I was pretty drunk and as was my fiancé, and we had sex (he is the only person I ever slept with, and the sex was consensual), I remembered that he fingered me, and it hurt. He had forgot to cut his nails and I think he scratched me. It's on the inner lip of my vagina, that's where it is itchy and burns a bit. Now, the killer and embarrassing part is that the very, very, very tip area of where the lips to the vagina start is itching like crazy. It's like the crease. I normally get itchy if I don't shave often, so I shaved it, but I don't think it helped. Ugh, any suggestions?
