IRL sex stuff
When you've boned enough IRL with low self esteem that you develop four entirely distinct styles for it, like martial arts.
Like seriously, I didn't realize it until I thought about how people's fursonas intersect with how they like to be Done, but I've certainly got Dog style, Rat style, Dragon style and even Iron style katas.
Because I'm not enjoying myself unless my partner is climaxing so hard that they're KO'd at the end and can't move.
