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.

Exaggerated portrayals apparently destroy desire more effectively than any repression.

The social problem is that we haven't come up with any alternative models. Our culture hasn't developed an ars erotica. Think, for example, of conditions in India or in Japanese culture and of how the erotic has been cultivated there. They're not as clinical and rabbit-like as we are.

There are young men who want thrills but no longer value sex, so they do completely different things, including aggressive things.

Some 95 percent of all sexual contact still occurs in permanent relationships. That's an impressive number.

Fantasies have to remain dirty. Cleanliness, scrupulousness and rationality are poison for eroticism.

We are all potential murderers, and we are all potential rapists and abusers.
