The Basketball Diaries by Jim Carroll

Here's one of my favorite passages from the book--

Tonight I just stuck
it out in bed, radared the scene and slipped into some
baggy jeans, a tee-shirt (stayed barefoot) and went out
and up. "Up" is my roof, and what I do is simply take
off all my clothes, stand around awhile, a totally naked
young boy, stare into the star machine and jerk myself
off. Is it strange? Maybe, but it's certainly the most beau-
tiful and exciting way of masturbating I've experienced
since I first began my steady practice of the art when
I was just turning twelve . . .   I don't
really think about anything while I'm in the process of
the actual tugging, least of all going into any of the heavy
sex fantasies I have to resort to indoors. It's just me and
my own naked self and the stars breathing down. And
it's beautiful.
