Aura of the mysterious is a minor perversion that a couple shares. A fetish that one of the two partners finds arousing, or a particular sexual scenario. Fantasies have to remain dirty. Cleanliness, scrupulousness and rationality are poison for eroticism.

Exaggerated portrayals apparently destroy desire more effectively than any repression.

While the Internet generally tends to have a stress-relieving function for adults - as long as they aren't inclined toward sex addiction - I don't see this being the case for adolescents.

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.

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.

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

The traits of our sexual culture are still speechlessness, loneliness, violence and not enough desire and love.
