Affiliate Marketing Secrets

I’m starting an online adult website & ordered Micro niche finder; it’s a software device that shows you certain “keyword” phrases being typed into Google. However, almost every single search is on the border line of “white women with black man”,” black girl dominates white girl”, “black man and white women” ect… Unfortunately this is No exaggeration or joke.
Actually the google search phrase “black man dominates white women” gets over 500,000 searches per day (I have the proof & can show the search results). I’m not making this up, I’m attempting to supply demand & this happens to be in high demand. And the excuse I hear from women most: “A fantasy is ONLY a fantasy& doesn’t count if you don’t live it out.”
Do you agree? It being a fantasy that holds no merit since not lived out?

basically i want to be tumblr famous, and i feel like a good way to do that is to have a funny, specific niche. (like blogs ike ‘white girl problems” or “ways to annoy people” or “dirty bieber secrets”) you know, blogs that only post about specific topics and specific themes…
so i was wondering, any good theme ideas? just something simple that a lot of posts could be made about and could be funny?
the more ideas, the better!
