the hair in my bum crack is bothering me. It always feels like it is pulling and gets very sore when I am sitting down. Last night I shaved the area, and although it has really stopped hurting, there is still one area near the top that hurts, almost stings. I have had someone look at it and there is no lump or anything like that, just a red rash. I've had this problem with the hair pulling for some months now, I am 21
