It's a known thing that men like younger women if appearance wasn't a factor. In most relationships the guy is usually older then the girl and younger women signal biologically that they are better for fertility. This explains why when a husband or boyfriend cheats it's usually with a younger more lively girl. Why else do u think older women tend to become more jealous and bitter towards younger women as they age.0THIS IS NOT RELEVANT ANYMORE
