>>41471388Some fetishes, like bdsm or foot fetishes, are easily explained. Feet are an erroneous zone and some people have the wires crossed in their heads. Violence, power, and sex are related and are kept in the same part of the brain. Attraction to someone much bigger than you though seems pretty alien in its origin. Fetishes are often caused by childhood experiences, and your parents were much bigger than you once. Alternatively, it could be a vestigial aspect of the reptilian part of your brain from species where the female is much larger than the male.
