Very interesting idea. I know quite a few roleplayers, and if there's one thing about lifestyle RPGers, they know how to express their sexual fantasies.
One thing I'd suggest is to really get into the freak/niche/fetish/kink vibe. Role playing is all about experiencing something that can't, or can't easily, be experienced in real life.
Right now, it seems like your site is plain strawberry sexual. Strawberry sex, though rather tasty, is easy enough to aquire so that role playing it is kinda boring. If you want to attract RPGers, add A LOT of sexual seasoning to the mix. Think themes. The more imaginative, the better.
