I read that particular website and I thought it was complete and utter rubbish. If you look there is an article talking about how the missionary position "The missionary position appeals to many Taken In Hand women for the same reason some other women thoroughly dislike it: because the man-on-top is the male-superior position."
I started laughing so hard at that. Dude the reason that we don't always like it is because after a while it’s fucking boring. I took a quick gander around but stopped after that. It just seems like someone who has some serious issues with women disguising their anger with a front of a life style. Maybe I am missing the point.
He takes quite a few stabs at people who don’t agree with him as well. The whole thing smacks of someone with a traditional Christian background who uses the bible as a reason to subjugate women. I wouldn’t give it any more time than it deserves, which is not a second thought.
