I understand your point. But it doesn’t quite explain why men, who are capable of rational thought, are willing to ruin their lives just to spread their “seed” around.
To some rich and powerful men being celibate and not "getting any" would make him feel like he was a failure. To them what was the point in amassing power?
The problem I have with this is the pretense of the wife and perfect family et al. Men that want the playboy lifestyle should ditch the wife, pay the money and go play. Sex is what keeps some (most) men from becoming really morose and melancholic. Even in a long term relationship a boredom factor can cause psychological issues. A women wouldn't understand. That is why there is a war between the sexes....
