When it comes to sexuality, people like to tell lies. It's only when it comes to money that they lie more.

Sexual desire declines after four to seven years. That's been proven.Because it's the most compatible with our spiritual origins. Father, mother, small family - that's the way we've developed our souls, the way we've become, and the way we feel safe, protected and loved.

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.

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

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.

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.
