undermyspell - i know gay men who can't sell gay sites for shit. running your text passed a gay man does not guarantee that he will know and like your niche enough to be able to market it.

research - egroups, magazines at your local newsstand, etc. that will help.

btw, i make good money and excellent conversions at many niches that don't turn me on in the slightest, including two i actively didn't care for. i have adjusted to them, however, after all this marketing.
