And there's also Portnoy's Complaint by Philip Roth- an insanely raunchy and hilarious novel:
"But what a mix-up of the sexes in our house! Who should by advancing on me, retreating – and who should be retreating, advancing! Who should be scolding, collapsing in helplessness, enfeebled totally by a tender heart! And who should be collapsing, instead scolding, correcting, reproving, criticizing, faultfinding without end! Filling the patriarchal vacuum! Oh, thank God! thank God! at least he had the cock and the balls! Pregnable (putting it mildly) as his masculinity was in this world of goyim with golden hair and silver tongues, between his legs (God bless my father!) he was constructed like a man of consequence, two big healthy balls such as a king would be proud to put on display, and a shlong of magisterial length and girth. And they were his: yes, of this I am absolutely certain, they hung down off of, they were connected on to, they could not be taken away from him!
I stand at attention between his legs as he coats me from head to toe with a thick lather of soap – and eye with admiration the baggy substantiality of what overhangs the marble bench upon which he is seated. His scrotum is like the long wrinkled face of some old man with an egg tucked into each of his sagging jowls – while mine might hang from the wrist of some little girl's dolly like a teeny pink purse. And as for his shlong, to me, with that fingertip of a prick that my mother likes to refer to in public (once, okay, but that once will last a lifetime) as my “little thing,” his shlong brings to mind the fire hoses coiled along the corridors at school. Shlong: the word somehow catches exactly the brutishness, the meatish-ness, that I admire so, the sheer mindless, weighty, and unselfconscious dangle of that living piece of hose through which he passes streams of water as thick and strong as rope – while I deliver forth slender yellow threads that my euphemistic mother calls a “sis.” A sis, I think, is undoubtedly what my sister makes, little yellow threads that you can sew with...”Do you want to make a nice sis?” she asks me – when I want to make a torrent, I want to make a flood: I want like he does to shift the tides of the toilet bowl! “Jack,” my mother calls to him, “would you close that door, please? Some example you're setting for you know who.” But if only that had been so, Mother!"
