These guys are so rich they can hire beautiful prostitutes whenever they want. Looks alone are dime-a-dozen, in the end it's personality that counts (the latter notably also holds true for non-gazillionaires).
Yeah, someone like Huang probably has beautiful women throwing themselves at him all the time and it's quite possible that he's taken many of them up on the offer already, it's just never come out before. A man who has access to such abundance of beautiful women may over time become more interested in things like personality, if he wasn't already more interested in personality before -- there are some men who care more about personality from the start.
I like to believe Bezos was still being yelled at to take out the trash and for leaving dirty pancake batter bowls in the kitchen sink.
