I was born with a foot fetish and I'm suspicious that everyone on my dad's side of the family has one desu. However they can also be picked up from experience. I went through a vore phase as a teenager desu.
Maybe ones from birth stay forever and ones you pick up can be lost, cause I've tried to cure my footfaggotry (cause it makes it hard to concentrate sometimes) through both inexposure and overexposure and neither worked but I randomly lost interest in vore one day.
