I'm a 41 year old woman, I know all about the birds and bees
If the date goes well and leads to sex who cares
It's a joke. In my experience, when you date someone you quite fancy, you end up having sex with them; and you can say you don't want a relationship or to get involved, but having sex with someone you quite fancy does tend to lead to feelings deepening and you having some sort of relationship.
The money isn't part of it at all, I earn my own money thank you, own my own home and car etc
The money is a part of it. He would not be in such good nick at his age without it. He would have less allure without the polish and selfcare it affords. It's just a fact of life that wealth influences healthcare. And the money is a part of it, as you have said the reason for your qualms about dating him was others might think you were a gold-digger.
He's also never dated anyone younger and it took him 7 weeks to build up the courage to ask me out so he doesn't make a habit of dating younger women
As you are 41, perhaps you have not been around a lot of older men, in terms of relationships. He is perhaps a unicorn.
Clearly you want to and will date him. Your defensivesness is a bit odd, to me, given you have asked for opinions on this man and the age difference.
As I said, good luck with it all.
