@V0RTEX777 Because if you think about it, a couple having the exact same fetish that is also not one of the popular fetishes has the chance of finding an animal you thought was extinct. There's also the fact that fetishes are a taboo discussion between opposite sexes, hell, even between same sexes sometimes, so two people having the same fetish may still avoid each other.
@tonymuffin Don't worry man, I read like 2 chapters a couple of years ago and dropped that like a hot potato. There are just some weird people on this earth.
