What should a woman be bringing into your life? What role is she supposed to occupy?
No woman you date or marry will fukk you better than a sex worker.
No woman you date or marry will clean better than a maid.
No woman you date or marry will cook better than a paid cook in a restaurant.
No woman you date or marry will give you the level of insight you'd get from a paid therapist.
No woman you date or marry will make you laugh and give you the kind of advice a friend of over 20 years or your brother/sister/parents will give you.
So then what role does she occupy in your life, and in what way does her dating history impede what you want her to provide for you? If you see women as 'free' caretakers for you who will fukk you when you want on your terms, then you'll primarily aim for young women. If you're looking for someone who will understand you and know how to act in tense situations, then you want someone who has lived as long as you have. It's that simple. There are life experiences like parents aging and getting sick, managing money and debt, knowing how to navigate the corporate world, knowing how to navigate your own emotions after experiencing setbacks in life like job loss or heartbreak that someone younger just won't have. If you want someone who you don't have to explain things to because they've already lived it, then you want someone your age. If you want someone who can think like you and speak on your behalf and predict what youll say before you say it, you want someone your age. If you want someone to service you, then you want someone younger because a person your age or older won't be on that wave.
You also run the risk of the younger person going through a quarter life crisis and realizing being married to you might mean having to take care of you as you suffer age related disease while she's still in good health and her friends are vacationing and enjoying retirement with their husbands. They see 20 years into the future and freak the fukk out and bail on the relationship.
