Think about it... As a man, in a relationship, we give something to the woman. But for the woman, what does she give to the man?
And no doubt, if asked, the woman would say first: "sex". But this isn't true (literally in most cases, and as a transaction for doing something for others) but if the relationship is good, isn't sex a mutually shared gift?
So seriously... what does the woman actually offer/ provide to you?
