I'm reminded of a female patient who was particularly aroused by the shape of her husband's shoulder. And this hint of perversion should ideally remain a secret for both partners.

The sexual revolution produced cultural convulsions that were unparalleled in the 20th century.

You're married to a woman who has no objection to another woman joining the couple. Then she brings in her boyfriend. Suddenly you realize - my God! - you can love more than one person. In fact, you can love several people at the same time.

It's very important to approach pedophiles and pedosexuals and offer them therapy. It's been my experience that you can reach your objective with what I would call kind-hearted, informed and enlightened patients - in the sense that they don't lose their desire, but that they no longer have physical contact with children. That would be the goal.

It's important for a couple to talk about their sexual preferences. On the other hand, the aura of the mysterious should be preserved.

There will be other forms in addition to our classic marriage. One is already looming on the horizon: polyamory, or having more than one intimate partner.

I maintain that we are still a largely ignorant society when it comes to sex. We speak incorrectly and superficially about sexuality. And when you talk about it too much, you run the risk of destroying its mystery.
