People want what they can't get. Older men love younger chicks and young guys have a thing for MILFs and cougars. When a woman objects to your age, it's a shit test. Basically they're saying you have lower value because you're not in their age range.
If a twenty-one year old girl objected to your age, you'd say...
"Did you know girls age faster than guys? Take models, for example. They peak at like seventeen. By the time they're nineteen they've passed their prime. They're middle aged. You're twenty-one, making you sixty-three in girl years"
When a woman tells me that I am too young for her, I'd say this exact line but add...
"You're practically a senior citizen... Don't take this the wrong way but I'm an active guy and don't think you could handle me with your cane and all... I should introduce you to my grandmother, I think she's more your speed."
This generates attraction in 90.2% of women.
Here's a quick explanation:
When a woman says, "You're too young (or old) for me," she's establishing the underlying meaning of your interaction with her as her being the Prize you're trying to win over.
This underlying meaning is what I call the "Meta-Frame."
But... when you respond to her with the line above, it proverbially picks her up by the nape of her neck and sucks her into your Meta-Frame that you're the Prize she's trying to win over.
