With an intelligent couple, it ought to be possible for the husband or wife to look for satisfaction outside the relationship - while always taking the partner into consideration, meaning acting openly but still discreetly.

I have the utmost respect for people who are asexual. I didn't believe that they existed at first. But they do exist, and their numbers are growing.

Perhaps the couple got married at 25 and now they're 45 and this is an option. And if a couple is still together, or perhaps finds its way back together, I like to say that it's forever. They belong together, it's a good fit, it's the right pairing. It almost gives me goose bumps.

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.

Good sex can be anything, including dirty.

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

Most young people seem to be behaving very intelligently: They look at things once in a while, but then they find it so idiotic and uncool that they just look away again. That is, provided they're not growing up in a family in which a drunk father is already watching pornos in the morning.
