Any interest in a line based on the Firefly family from House of 1000 Corpses/The Devil's Rejects? I have some ideas. Lots of dark taboo weirdness to be had! If you bring nothing to the table, don't bother - I'd write a fanfic if I wanted to put in all the hard yards myself.
How about something based on the TV series Spartacus? Not House Batiatus specifically, but the whole villa/ludus, master/slave dichotomy. Maybe a supernatural spin on it? I'm all for creativity.
In both cases, yes, I am happy to play male roles, and I'm pretty hard to squick out as well. However, I am not interested in coming up with every single twist and turn in the plot. If you just want someone to write a story for your wet noodle tween to flop around in, move along!
