I tend to try to find what works best for them to enjoy the activities. I enjoy most any position. In fact, I can't think of any I don't like!!

Just wondering ? RED !
Some of us just can't get to where we want in certain positions!! LOL!
So let me ask, would that be if he is a fat fuck or a skinny guy? Just playing!
Not sure what it's called, I call it the scissor. The woman is laying on her side with one leg up and the man straddles the leg that's down and holds the other leg up. I've found that you get increased tightness and can get some great thrusting action and one hand can roam around, grab some boob, finger some ass, whatever strikes your fancy. Good for both anal and vaginal action. If you haven't tried it, you should.
your fingers deep in my ass !
ummm i love it ! 
I love doggie style best! But a very close second is missionary. I am really small inside, with a short passageway, so CG can be painful for me if the man is too long, but I love the control I can have on top. I am working hard on my Kegels, so I like trying them out on my partner while in CG position. They also work well while being taken from behind (and in missionary... well, in any position, I suppose). If the man is long enough, he can have a great time while I am flat on the bed on my tummy and he is taking me from behind. The combination of my glutes and my kegels make for a very good time.
But I am up for most any position someone wants to try!
And then there are always the oral positions...yum.
