I have dated many guys from ages 17-51 and I've noticed that for the majority, most guys my age don't have chivalry/class. They expect sex after the first date and continuously bug you for it and are so desperate for it. I've never had an older guy do that, they are always very charming, respectful, and classy. They open doors, are polite, respectful, and mature. I'm just wondering, what about most guys in my generation has them lacking chivalry and class?
