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.

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.

Sexual desire declines after four to seven years. That's been proven.Because it's the most compatible with our spiritual origins. Father, mother, small family - that's the way we've developed our souls, the way we've become, and the way we feel safe, protected and loved.

Good sex can be anything, including dirty.

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.

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