Second paragraph of third story (“Coming-of-Age Day”, by A.K. Jorgensson):

But you got some funny answers.

A 1978 anthology from Pan, including stories by Robert Silverberg, Thomas M. Disch, A.K. Jorgensson, Anne McCaffrey, Brian Aldiss, Hilary Bailey, John Sladek and Michael Moorcock. I’m afraid that despite the stellar array of authors and the potentially interesting subject matter, this is not a great collection; several of the stories depend on a rather rapey concept of consent, the Aldiss contribution is frankly incomprehensible (I see that this is its only publication apart from its original appearance in F&SF) and the Moorcock is an excerpt from Dancers at the End of Time that I already have in two different editions. Hilary Bailey’s “Sisters” is the best of these, and it’s more about bio weapons than sex. You can get it here.

This was the shortest unread book that I acquired in 2016 on my shelves. Next on that pile is The Shape of Irish History, by A.T.Q. Stewart.
