I maintain that we are still a largely ignorant society when it comes to sex. We speak incorrectly and superficially about sexuality. And when you talk about it too much, you run the risk of destroying its mystery.

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

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

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

Good sex can be anything, including dirty.

There are many options in a marriage. If the couple has been together for a certain amount of time and has a certain amount of liberalism or life experience, it could be the kind of relationship in which one partner ventures into the occasional affair, which is then forgiven. This only happens every 13 years on average, but it obviously does occur.

I will always be referred to as a theorist, but I was only a fellow traveller with a degree.
