If you think BoEF was kink for the sake of kink - head out to find Black Tokyo in PDF at the enworld store. *cringe* If there was ever a book that reeked of prepubescent male misogeny - that is it.
While I have never even bothered with BoEF, I've found that for most of the RPG world - sex in gaming is not a subject that can be authored with taste, dignity, and actually be able to sell copies. Let's face it - the sick stuff is what makes people buy it. Nobody bought BoEF for a table do randomly determine sex of an unborn fetus - they bought it for scantily clad fantasy chicks slinging spells called "DO ME, BABY!"
