Good sex can be anything, including dirty.

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.

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

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.

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.

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.
