Good sex can be anything, including dirty.

Internet sexuality shows that we're becoming more and more self-involved. I'm talking about self-sex.

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

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

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.

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.

It's important for a couple to talk about their sexual preferences. On the other hand, the aura of the mysterious should be preserved.
