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.

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.

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

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

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.

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