this obsession older guys have with younger women is always rooted in some sort of mental or emotional flaw. Yeah dudes will cite biology or whatever but most of the times it is an ego thing. Older guy never had success with younger women back in his day and now he wants to make up for lost time. I've known more than a handful of dudes like this who daygame college campuses despite being 30+, go to college parties, hit up college bars, and try to go to young nightclubs.
Very rarely, if ever, have I seen these guys actually pull. Most of the times, everyone is sort of laughing at them while the younger woman is usually going off with some Chad her age. Almost all the time these guys swear off women their age and obsess over chasing younger women, often failing and coming off as creeps in the process. The success is rarely if ever there.
