I saw a video the other day about a 70 year old billionaire who got a 40 year old girlfriend within days of breaking up with his old girlfriend. He was interviewed about his Ferraris. She was standing behind him and cuddling his hair, as he was being interviewed.
I would argue this also falls under paid sex.
I have a chubby friend that married a hot Thai chick.
One day, he looked at her and said "you're getting fat, you need to lose a few kilos". She told him he was putting on weight too.
He turned up her and said "I married you for you looks, you married me for my money. I still have the money"
I was impressed. It was pure alpha.
Obviously- she lost no weight
