That is just not true. You state your opinions as if they are fact.
If anything, older women not being able to conceive is a positive. Young men can fulfill their sexual needs without the fear of conception. Many young men actually seek out older women--it's just not documented, painted nor written about (because traditionally artists, writers, and scholars alike have been men). Younger men being attracted to older women are not and do not remain exceptional--I have seen it with my own eyes observationally and now experientially.
I think you have very misconceived notions and it's understandable because a certain group of people, and the ones who have been most vocal, have been repeating this narrative for a long time and you happen to just imitate them, continuing to repeat outdated and even incorrect ideas.
I hope you will go out into the world and learn from others and open your eyes and ears.
