EROS IN ORBIT
Science fiction discovers Sex! Edited by Joseph Elder, published by Pocket Books, May, 1974.
From the back cover:
Does sex have a future?
In this mind-bending book, ten top science fiction writers answer that question. Among them are stories of:
* man's first mission to Mars, with all the astronaut's physical needs provided for
* the boy genius who sets out to invent a death ray and comes up with a powerful aphrodisiac instead
* the machine that permits a person sitting alone in his living room to make love to six or more partners simultaneously
* the sex life of disembodied human brain commanding a flight to the star Antares
