I remember reading that the things that made us uncomfortable as children become turn-ons as adults. That would explain all the BDSM archetypes of the headmistress, clergy, etc. It would certainly explain an obsession with getting fat if we were shamed for it as kids or taught that it was the worst thing that could possibly happen to us. I fall into the latter category. As a kid all the normal movie/cartoon themes were terrifying but made me feel a certain way at the same time. As an adult I get off on seeing other people give themselves over to gluttony & hedonism and I give in quite regularly myself.
