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

The sexual revolution produced cultural convulsions that were unparalleled in the 20th century. The female sex was historically sexualized and required to have orgasms for the first time. Sexual "deviants," particularly homosexuals, achieved partial emancipation.

Perhaps the couple got married at 25 and now they're 45 and this is an option. And if a couple is still together, or perhaps finds its way back together, I like to say that it's forever. They belong together, it's a good fit, it's the right pairing. It almost gives me goose bumps.

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.

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.

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

The sexual revolution of the 1960s was mostly a movement of young people. I felt that the so-called "free relationships" were overrated.
