There was a 70's song that mentioned " backseat rhythm ". And if you are with enough girls, you understand what they are talking about here. When you make that thrust, the girl pushes back at the same time to maximize the penetration. Most girls have it, but some do not.
I was with a cute little AA last night. Very affectionate, great kisser, gave a great BJ. When I turned her over to do doggy, I got to look at this fine tight pooper. But when I began my pumping from behind, she would push back and the thrusts just did not match up. I tried stopping and starting over a few times. But this position was just not going to work for me. Her timing was just off. So turned her over and did some other positions where I was in charge of things a little more.
But can rhythm be taught ? Or is it just something that is natural ?
