A 22 yr old female is not a woman, she's a girl, a young girl. With that are issues that are just not worth dealing with, i.e. lack of experience, immaturity, completely different perspective then yours, un-worldliness, confused emotions, giggling...
Sure, there are exceptions, and there are wild hotties that know how to please a man at a young age but once the orgasm subsides and you're left laying there with this spitfire, what is there in common.
You: "Baby, that was incredible. I am completely spent, come here and lay next to me"
Her: "That was fun (giggle). I texted Gina and she said there's this rad party over at Brad's. Everyones gonna be there. I'm hungry can we get some pizza. My dad has the same watch as you"
Now a mature woman...
You: "Baby, that was incredible. I am completely spent, come here and lay next to me"
Her: "uuummmm I love the smell of you when I dig my nose in your neck. I am so fucking horney again. I want more. Let's stay in bed all night and not leave the room, order in some dinner later. I want you to make love to me again.....and again......and........"
When I was a young man in my early 20s I had a gf the same age but I was "taught" about female sexuality from ladies in there 30's and 40's. The lessons were priceless.
Young women need to experience the missteps of young guys in order to hone their sexual prowess. Once they become seasoned, then they're sexuality blossoms and continues to blossom as they mature.
So for you guys who love the young girls.....enjoy....but know their limitations and stop whining when they don't respond in the way you hope for.
