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.

Most pornographic images are simply too repulsive.

We are all potential murderers, and we are all potential rapists and abusers.

The things that could be derived from the sexual sphere - happiness, endless fun and the end of capitalism - were grossly overestimated. The symbolic overglorification was downright unbearable.

Sexual desire declines after four to seven years. That's been proven.

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.
