Why are men attracted to younger women?

I have heard alot about how Men are attracted to younger women because of their biology and how "fertility" plays a part in it which is absolute bullshit made up to excuse their pedophilia and fetish, because if it was in their biology, they would only be attracted to women during the time period of ovulation,as we see in nature when dogs are only getting on it when the female dogs are in their heat.

Let's be real if it was related to fertility,it would be other way around, because only the sperm quality degrades as the carrier ages but the quality of eggs remains consistent(though the quality of eggs do decline,it doesn't automatically happens after you age a day more than 25 ,it's a natural process)which also contradicts to the argument "women are born to only give birth".women have menopause which means we can't give birth after a certain age but men produce sperm untill the day they die except some exceptions,which means men are the one born to make babies lol.

Next time a man tells you how he prefers younger women,he's talking about his fetishes,not fertility.
