Aura of the mysterious is a minor perversion that a couple shares. A fetish that one of the two partners finds arousing, or a particular sexual scenario. Fantasies have to remain dirty. Cleanliness, scrupulousness and rationality are poison for eroticism.

You're married to a woman who has no objection to another woman joining the couple. Then she brings in her boyfriend. Suddenly you realize - my God! - you can love more than one person. In fact, you can love several people at the same time.

There are pedosexuals who, even if the court forces them to go into treatment, do not pursue it or cannot pursue it.

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

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.

There will be other forms in addition to our classic marriage. One is already looming on the horizon: polyamory, or having more than one intimate partner.

Most pornographic images are simply too repulsive.
