Whilst not exclusively, yes, ordinary sex seems so boring in comparison.
But I never thought it was an Aspie thing, in my case the only interaction I got as a child with my so called parents, was to be beaten and humiliated, I never ever got even a hug from my Mother, and she only ever said a nice thing to me once when I was 8.
So, I think you learn how to be loved from your parents, they taught me I was only worth even being acknowledged by being kicked in the stomach or strangled.
It also means the only emotion I ever learnt was pure fear, so now Iam grown up, somebody being nice to me, maybe stroking me or something, does nothing for me, in fact I have to stop myself from laughing at the impotence of thier attempts to reach me through barriers that only extreme actions can.
