Gay Demon does have a webmaster resource area at http://www.gaydemon.biz/links/
You can submit content stores, affiliate programs, web hosting, etc.

In Gay Porn still has a big area and a link for new listings. Some of his old listings (still up) have bad links or go to programs that aren't around any longer.

X-bix, Adult List, Cozy Frog all have web master areas for sponsors and programs.
