We talked about it once.. there isn't much to talk about as I'm asexual and think sex is for dirty old men and for people who are trying to make a baby. I'm not a dirty old man and I don't want/have never wanted a baby, so I've never had sex and I've never masturbated.
We talked about it quite theoretically - whether I'm truly asexual, or just too young, or if it's being influenced by the sexual assault that happened when I was young.
