Your post and the responses made me realise that that uncomfortable tingling is a body memory... I was molested as a child and to this day still get that tingly feeling. "I am also asexual (don't like sex) thankfully my partner is okay with that :)
I still deal with the guilt, and I'm embaressed that I don't like it. It seems to be everywhere and I have a horrible time dealing with the idea that I'm wrong to not like it.
