Never been on top, what do I do?

It's really not that much different, except that you get to control the pace, and depth of penetration. Plus, he gets to rest his back.
The less you think about it, the better it will be. Just get on top of him and start moving up and down, and sometimes around in circles. There's really not much to it to be good at it.
It happens to be my favorite!

Do it, it really doesn't matter if you know what you are doing anyways cause its going to be good for him cause you are in control of that situation!! Just do whatever feels good to you and it will be good for him to I'm sure!!

It's really simply. You climb on top and move your hips and ass . Grind on it up and down slowly. If you want it slow take it in slow motion. Stroke the dick to like you've never before. And just enjoy the feeling being on top. Also enjoy looking at the arousal of your mate.

You know until you do something your never gonna know what your doing. I'm sure your first time you didn't even really know what you were doing but did it anyways. If you want to just do it is all I can say.

Relax girl, your in for a treat, woman on top is one of my favorite position, let you guy lie down and straddle him, let him or guide you as you enter him, you can move your hips by gyrating while he pushes your hips down.. LOL
