Yes, the scrotum is ticklish on me. Your subject made me think of something. I cant remember where I heard this, not from anyone on TMF, it was some time ago, but I once heard a story of a woman who was so ticklish on the inside of her vagina, that she squealed with laughter, and felt like she was being tickle tortured, every time her husband and her had intercourse. I cant remember how they resolved this, but I do remember that they said it was a detriment to their sex life for a while. I thought this interesting.
