You tried watching good granny porn yet? I didn't have this fetish until I watched one just for the sake of it. From that moment on, I started noticing the attractive qualities of gilfs. There are some really good amateur ones on xhamster.
I disagree from experience. Starting off, most older women hate the idea of fucking with a younger guy. They think we are below them, that we are mere children and immature, they can't see us as males, even young Chads. So you already start with a minority of older women. And then among those who are willing to have sex with younger guys most of them want the young Chad. So it's actually harder to ascend with a milf or granny than with a foid your age or younger than you.
Younger foids are the most likely to give in to you, as crazy as it sounds it is true. Young and beautiful women have lower standards than ugly and old women.
