In an interview on Sex and Marriage

The Joy of Sex by Alex Comfort.

This is important in that, like the Marie Stopes, it was the first book of its kind. It describes itself as a ‘gourmet guide’ to sex and it was written 50 years after Stopes and takes thing on a stage. It has those wonderful line drawings and I remember demolishing it as a guide on how to do it. The 60s were supposed to be swinging but it didn’t really start until The Joy of Sex in 1972. It seems so innocent really now, all those daring explanations of S and M and positions, but it was before Aids and people were so optimistic. It was as though we’d discovered sex and free love. It was only 40 years ago, but since then Aids and all the implications of free love makes it look dated and innocent. Marie Stopes still has more to offer contemporary couples in terms of strong, punchy sex advice for men and women. Of course there’s more to sex than just getting into positions. It’s about what’s going on in your head space, and sex changes as you change.
