Adult Friend Finder, my man. Before that I used to score big by skimming Yahoo profiles. Basically if you found a woman whose yahoo profile had a picture, there was at least an 80% chance it was a MILF looking for a hook-up.

Yahoo completely fucked up their whole profile system several years ago, though. Now it's much more like Facebook, and much harder to find promising results. I've heard that you can find real women on Ashley Madison, too... in fact I know a couple of women who are on there, but I've never used the site personally. But it has been proven that a large number of the profiles there are fake and they generate fake messages to male users to trick them into getting premium accounts.

EDIT: It also probably helps that I have a very wide range of tastes. I like 'em big, small, short, tall, black, white, or brown, younger, older, etc... so long as the face is pretty and I can make her laugh, I'm game.
