Big big big into oral stuff, like that long grapefruit animation I made was a labor of love because of how much I enjoy it, stuffing as many fun mouth moves in there as I could. As for stuff I only like in art, the first thing that comes to mind is really risky public stuff where you'd probably get caught immediately, also anon hookup stuff/gloryholes, in real life doing stuff with friends/partner is a lot more my style
