Why not both?
I read a statement from a gentleman concerning the money he pays a companion. The money goes toward his happiness, not hers. He doesn’t pay her more money to put a smile on her face. But my argument is, unless you’re slightly masochistic, how can she make you happy without a smile on her face? I’m not endorsing paying a woman more than what you’re willing, but negotiating usually isn’t the best way of getting the best out of a lady.
Whatever a lady’s price tag, it makes her happy. What you have to ascertain is if she can make you happy for the price.
