Full Idea
It seems strange for a man and a woman to give no more thought to the question of whether they should engage in sexual intercourse than to the question of whether they shoud play tennis.
Gist of Idea
Does engaging in sexual intercourse really need no more thought than playing tennis?

A Reaction
This strikes me as a reasonable point, but times have moved on since 1969, and for plenty of people nowadays playing tennis is a bigger issue than having sex, because of the time, equipment and effort involved.
