Most pornographic images are simply too repulsive.

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

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

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.

Sexual desire declines after four to seven years. That's been proven.

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.

I'm reminded of a female patient who was particularly aroused by the shape of her husband's shoulder. And this hint of perversion should ideally remain a secret for both partners.
