I love it when he pounds me from the back and pulls my hair so I can face him at the same time... oh I love that... there are many other positions I love, but out of these choices, this one is my favorite.
Hm. Part missionary, with him kind of off on one side or the other. I can't explain it. He's bigger than I am, (at one point, when I was really thin he weighed double what I did, and I think he does this so he doesn't crush me) or with a leg thrown over his shoulder. Side lying, either facing each other or him in back. The Arrow, it's kind of like doggie, but the woman is flat on her belly, and the man has his legs around her, this works for PIV or anal.
I don't like Cowgirl or Reverse Cowgirl all that much. When he was younger, it was easier. Hell, when I was younger it was easier. We tried for years to do it with me over the edge of the bed, but he's too tall. I also don't like my legs dangling. Same for standing, we have a 15 inch height difference and we can do it this way, but it isn't fun. He humps me in the kitchen or wherever all the time standing up, but actual PIV in this position doesn't work well for us. I'm on my toes and he's basically squatting. Not pretty.
I have a fused spinal column, so my flexibility and range of positions are pretty limited. Missionary is the most comfortable for my back, but it's also the most boring for my husband and me. We've been trying new positions lately, but it seems like we always fall back on doggy or cowgirl.
