A man 37, almost 38, never married, no children. What does that say about him?

Well-endowed, owns his own construction company.

Handsome, looks young, takes care of himself very well. He's into active sports, flies to warm countries. Now he's studying to be a psychologist for some reason. He says he's planning to have kids in the future.

I also know that at 34 he was courting a 17-year-old girl. I don't know how serious his intentions were, she turned him down.

I would like to know my opinion, and I would like to know who has experience with such people. I like him, but something about his background embarrasses me. I'm younger than him, 21. I would like to marry him, what do you think?
