I got more than 10,000 surfers from Jays XXX last month. I calculated to 10,000 but then I got lazy and didn't calculated rest of my domains.
I don't want to be a rude, but sites you have build are male domination/female slavery and your ads are a little bit of lame as are the names of sites. This is subniche of it's own and surfers who search it know exactly what they want. That site, Slaves in Love, is very good and I have done some nice sign-ups with it.
The name of the site says it all. Slaves want to be punished and humiliated because they get their satisfaction from that. There is lots of real life slaves in this world, both men and women. I know both and I have been watching the sessions.
Here is couple of sites I have done:
http://www.hottyporn.com/female-slave/
http://www.hottyporn.com/bdsm/01/
If there is fetish parties in your town, go there and talk with people. With BDSM you have to know what you are doing.
