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.

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.

Key feature of sexual revolution is the large-scale publication and commercialization of details that were once secret. Sexuality has been trivialized. The interesting thing about this is that exaggerated portrayals apparently destroy desire more effectively than any repression.

With an intelligent couple, it ought to be possible for the husband or wife to look for satisfaction outside the relationship - while always taking the partner into consideration, meaning acting openly but still discreetly.

Good sex can be anything, including dirty.

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.

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.
