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

Exaggerated portrayals apparently destroy desire more effectively than any repression.

There are many options in a marriage. If the couple has been together for a certain amount of time and has a certain amount of liberalism or life experience, it could be the kind of relationship in which one partner ventures into the occasional affair, which is then forgiven. This only happens every 13 years on average, but it obviously does occur.

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

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

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.
