The sexual revolution of the 1960s was mostly a movement of young people. I felt that the so-called "free relationships" were overrated.

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.

For people who are desperate and searching, sexuality on the Internet offers an incredible release.

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

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.

Sexual desire declines after four to seven years. That's been proven.

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.
