sexkey sends lots of traffic in gay and straight niches. they're pretty easy to sell.

i had no luck with mansites myself, but that's just me. i didn't have much luck with fnp, either.

i do fine with straight sites on freeagecard, but my only gay site didn't do too well there. to be fair, i didn't try too hard - i moved the site to the gay avs i do best with.

good luck finding your solution!
