I can very much relate to feeling it doesn't belong, though I've never been comfortable with it myself. It is the biggest source of pain and anguish for me.. Even in my past relationships I have never been able to involve my own genitals during sex stuff, I just can't bring myself to do it! It feels so absolutely wrong and kills the mood for me instantly, I just feel sad and broken right away.
One past relationship was really pushy about involving it, even though I had explained I really didn't want that.. I didn't buckle, but even though we were in bed together I felt sort of violated and wounded that my wishes were not respected..
Absolutely cannot wait to get my nether regions sorted, but I hope my hatred for it doesn't increase much with HRT cause I don't think I could stand any more despair in that regard!
