I will leave detailed explanations to domain experts. An example I'd hold up would be when Leonardo DiCaprio catches flak, loudly and publicly, for consistently dating women only in their early to mid 20s [1] [2] [3]. Is it biological? Yes. Is it legal? Absolutely. Do people still vocally decry it? Very much so.
When does he catch flak? Leo is one guy, you could list a whole bunch of ceos and famous people's private lives as counter-examples. Bill gates has been married to Melinda forever.
That story is an advertisement for Leonardo, not a fundamental truth about human sex lives.
