Extreme BDSM niches - making money where no man has ever made money before?

Well, I have read posts and tutorials left and right, and I've come to the conclusion that I'm gonna try and promote BDSM with a special niche. At this point I'm just as interested in trying something new than in making money. So I wanna try promoting the smaller sites, and not giants like Hogtied etc. yet.

I've come up with http://webmaster.bloodbitch.com and I wonder if promoting this would be profitable.

Any thoughts on this - and suggestions are welcome!
