I have once talked to (well, more like interviewed) my mother about sex. I don't remember anything about it (I've had 51 ECT treatments and they leave me with barely any recollection of my life) except that I wondered about how you go about having sex - you (mum) want to, but how do you know dad wants to too and wouldn't rather sleep? I don't recall my mother's answers, but I imagine I had several questions like that. I have Asperger's and I like to 'gather information' on how about you do certain things in social situations. Even though sex did not and has never interested me.
