Ok, I'm looking at doing a BDSM site soon, and would like any thoughts, insights, knowledge, terminology and explanations, marketing approaches, etc on any and every aspect of the niche and the people who pay to see that sort of site ... and I am interested in both the Gay and Straight marketing aspects.

Stuff like, what's the turn on, what "sub" categories fit, ie: leather, fisting, vac bags, whippings, spankings, other terms that I'm blanking on ...LOL
