If you won't do this for your guy, then you are missing out, and so is he.  Real men having great sex eat each other's asses. Most girls won't do it, but men aren't girls.  So, eat him, and expect him to eat your hairy hole, too.  It's manly, carnal, and so hot-sexy-nasty in the way the makes man-to man sex the best.  It's the Clan of Men Way.
