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.

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

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

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.

Just go to an auto show, and you'll see all the signs of sexual arousal in the men: shiny eyes, tremors, sex flush. An acute example of the need for professional sex research.
