Good sex can be anything, including dirty.

I have the utmost respect for people who are asexual. I didn't believe that they existed at first. But they do exist, and their numbers are growing.

Sexuality is pushed back more and more and people try to replace what they've lost with other forms of excitement.

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

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

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.

Just go to an auto show, and you'll see all the signs of sexual arousal in the men: shiny eyes, tremors, sex flush. An acute example of the need for professional sex research.
