I've always had feelings for older men. Why do 25 year old women like older men?

Power and money. It depends on the particular woman and man of course. But after physical appearance, younger women often talk about liking "older" men because they're more sure of themselves than men of their own age. They've achieved a certain level of power & prestige in their career. They usually make more money than men in their early 20's. Some may also unconsciously like the "father" aspect of these men.
