It's fair to assume that all men want sex, that's why the friendship test, and dating exist, to use that as a testing ground.

If he asks for sex while dating there's your answer, marriage is a commitment, he puts his monetary value up in exchange for your intimacy.

And yes, I know true love, or whatever it is people believe these days, but in all honesty, it's transactional in modern society, and most women give up their cards quickly because they believe they can "capture" a high status man that way.
