I don't know whether it's a fetish, but I'm attracted to intelligence. No, not ''look at all those diplomas'' intelligent, I mean the basic form. Being capable of analysing and verbally communicating.
I have yet to confirm it as we are the only ''intelligent'' species on the planet with the fore mentioned human-ish intelligence. But if my attraction to fiction is any clue, I don't think I could find anyone- or anything- sexually repulsive physically.
I understand this can viewed as somewhat controversial. I apologize if it was offensive to you.
