Well, maybe cause older men are set in their ways, settled down, aren't just looking for sexual things, have more patience etc.. I will admit since i got in my late 30's into late 40's now i have more patience and would go out on limb for a younger woman particularity but i do respect all women.
Life was different in our era. We didn't have cell phones or the Internet. You always want what you can't have, just like when you're on vacation. It really wasn't that special, but we did the best we could.
Sometimes a young lady just want a grown up man not a boy. If you are mature enough and know what you want I say explore. It seems to me playing with a video game or hanging with buddies is way more important these days than having arm candy to be with. I see the young guys on our block and think do they just not know anything about how good it is to be with a sexual partner? These guy's don't even have chicks hanging out. WTF? When I was young I saw 3 girls a day when I was in high school and kept a supply of 6to7 a week. Never breaking the cardinal rule ( never piss a girl off ) because if you do there goes all that free networking. ( she tells a friend and her friend etc.) I did settle down at 19 and was married but I still had a problem with a wandering eye. I did get serious also if that's what pleased a lady. In my day we knew the best gift a girl could give was herself , we appreciated a lady !
Try traveling to other countries, you will learn that USA is the most racist country in the world! People in other cultures love a little color on your skin! I love dark men, but ended marrying a white Caucasian, for his intelligence, his manners towards me. He could had been any color, but it cannot replace a good conversation and politeness!
