It can only be my general distance from gay literary culture that has kept me from learning before now about the poem Please Master by Allen Ginsberg. Here are just six lines to give you the flavor, if like me you were unaware that such a gloriously explicit thing existed:

Please master make me go moan on the table
Go moan O please master do fuck me like that
in your rhythm thrill-plunge & pull-back-bounce & push down
till I loosen my asshole a dog on the table yelping with terror delight to be loved
Please master call me a dog, an ass beast, a wet asshole,
& fuck me more violent, my eyes hid with your palms round my skull…
