About 3 weeks ago, my partner accidentally bit my clitoris while he was administering oral sex. It bled lightly for a day or so, was a little tender and I thought it had healed. About a week ago, I began to get really tender there again, and then I noticed some swelling, and a lump... followed by intense pain whenever the lump/bump was touched. The pain has gotten so bad I can't walk without it almost throbbing... and I woke up this morning to sheets covered in blood. I'm not thinking it's an STD, but I could be wrong?
