Michael Parent has a friend. “A friend who skydives weekly — he loves it,” explains the professor in the department of educational psychology at the University of Texas: “You’d never get me to do that”.
This is a story he tells to introduce his line of work. In just about every walk of life, says Professor Parent, “we accept that different folks have different preferences. But we often seem to see sex as something that everyone has to like and want – or there’s something wrong”.
