If you are one of those fratty college guys posting on Craigslist looking for MILFs: Go to one of the New Kids on the Block reunion shows. There will be plenty of drunk thirtysomething ladies looking to recapture their youth (or someone else's). If you are unable to fulfill your fantasy of making love to an older woman who may or may not have given birth in this particular scenario, you should probably just move on.
I cringe at the possible traffic these keywords (MILFs, New Kids on the Block, fratty college guys) are going to bring in. I have no one to blame but myself.
