I Remember Gravity — James Trivers

On the militaristic Homestead, Velcro lines the bottom of objects
and the soles of shoes to hold things down. The ten-thousand-manned
space ship has meandered on the far reaches of the empty universe for
thirty-five years. Nonetheless, the ship's shops, schools and
services attempts to recapture the amenities of suburban life in the
now long-gone earth.
A psychiatrist suddenly has a revolution on his hands. Entire
demographics of men, women and children are acting out in a sexual
compulsive manner. People are flocking to the space ship's boiler
rooms where they shed their clothes, float, and fluck anonymously.
This spins the shrink into a quandary, he tries to rein in his client's
impulses but he too is swept up in the ship's zeitgeist.
