“I want”, “I want”, “I want” and – surprise, surprise “I want”!
Have you ever considered that a relationship primarily is a give and then a take (if at all)?
Have you also ever considered that by the time your desired children would go through the biggest hardships and troubled times of their lives, i.e. their teenage years, you’d be an aging grandfather who himself requires support, care and assistance?
You would be in no condition to lend them the necessary support, the reliable emotional or physical stability that they require to grow into independent and responsible adults. By the time they’d graduate from university, you’d have to be carted in in a wheelchair to attend the ceremony.
You say you “have good plans for [your] future? Yes, your future and yours only! Who would take care of your desired ever so “much younger woman” when she gets old? You would condemn her to sit alone with your children because you’d be deceased and there will be no-one left to take care of her.
Age is not “just a number” it accounts for the lifespan that we have to dwell on earth and since you’re downright blind to that fact, you’re neither suitable, nor fit for a relationship. You want to “protect her from experiencing the ugly things in a romantic relationship” - then do the obvious and steer clear of any woman who's father or even grandfather you could be!
She wouldn’t even have to believe that “all men are pigs”, she would simply need to understand that you’re egomanic. You’re looking for “a woman who is innocent and a bit naive?” Only a blankpoint crazy kamikaze woman would give herself away to the dire prospect of wasting the flower of her youth on such an egoistic aging fossile! (So much for a woman who is "hungry for life”)!
Your post leaves me exascerbated and ashamed of being a man, really! It is precisely people like you who give decent men a notoriously bad reputation.
With such an egoistic view in mind, you, in all earnesty, wonder why you are still single? Maybe because it is good that way, so keep it that way!
