Whenever I have sex with my fiancee I experience intense pain. The moment we try to start it is unbearable, and feels like I'm being torn apart. We thought maybe it was a dryness issue, but lube did not resolve the problem. After sex I am extremely sore, and it feels as though the bottom of my vulva is ripped. It isn't my vagina that hurts, only the skin around the outside. Any ideas about what's wrong?
