Perhaps the couple got married at 25 and now they're 45 and this is an option. And if a couple is still together, or perhaps finds its way back together, I like to say that it's forever. They belong together, it's a good fit, it's the right pairing. It almost gives me goose bumps.

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

The things that could be derived from the sexual sphere - happiness, endless fun and the end of capitalism - were grossly overestimated. The symbolic overglorification was downright unbearable.

Exaggerated portrayals apparently destroy desire more effectively than any repression.

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

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

The sexual revolution produced cultural convulsions that were unparalleled in the 20th century.
