Me wonders if some men are voting in the poll, considering that doggie is the winning position so far. Most of the woman I know prefer missionary for lovemaking, and on top when the want to come (I'm fortunate in being able to come in virtually every position).
One of my early lovers initiated me into doggy. He was very athletic and into all sorts of positions -- he had a kama sutra book in his bookshelf. It was all new for me, being a college girl whose early lovers mostly wanted to hop on top and come as fast as they could.
Doggie provoked some mixed emotions. It felt very different. He was average size, and could really get in there when he fucked me from behind. It obviously felt great for him, because he would come pretty quickly once we switched. I liked trying something new, and I loved it the first time I looked back and saw his face: he was so happy and into it. I realized he got off seeing my back and ass, seeing his cock disappear into me, and, he said, it was a very tight feeling. I didn't like not being able to see his face.
Since then, I have been fucked doggie by most of my major lovers. I learned to find the position, with my head down and ass high, that made it work best. One well-hung guy fucked me with my legs inside his legs, if you can visualize that. That way he could fuck me with abandon without hurting me. Skilled lovers would fuck me with their cock coming in at different angles as they rotated their hips -- major turn-on. I love being bent over a piece of furniture, or even just head down standing there, while the right-height man fucks me standing up, my dress still on. Eventually I lost my anal cherry, too.
I learned to be aroused by the primal nature of it, not seeing him, being taken from behind...if a relationship was getting old, I will confess to fantasizing about another man while the current boyfriend fucked me that way. And some of my post powerful orgasms have "come" from being taken this way.
But my favorite all-time position? Probably not. But I'd love some comments from women (or men)...
