How can men give up hard earned money to just fuck a woman?

I have my best friend who is in police department. He's at very good post in his department. Earns a looooot.

But we fuck each other when he misses fucking. Specially when some stress is going on his life he comes to fuck me and lick me.

He gives me fortune like money and i wonder how weak men are to give away so large money just to be physically satisfied
