I'm a big fan of missionary with one or both legs over the guy's shoulders. Can you say balls-deep? I really like doggystyle too, but I've yet to pull it off without literally passing out. Maybe that's a good thing...
Decisions decisions.....well from the ones you have listed I would have to go with doggystyle. My wife loves its when I spank her on the ass and reach around and play with her pussy.
But to choose from any position it would be a toss up between doggystyle and 69. If we have time (ie kids are occupied or with relatives) and we are really hot n' heavy missionary is decent with a few twists. I put her ankles on my shoulders...grab her tight round ass and use slow long thrusts, if this is workin the juices are flowin and her eyes roll back into her head then a little finger in her anus works good....
I love when I'm laid across the bed with my feet planted firnly on the floor. He kneels down on his knees 'tween my legs. I lower myself onto him. It allows for alll kinds of tit and clit and ass play while I ride him!
Missionary...with my knees back as far as they will go towards my shoulders with my ass up off the bed a bit...allows deep penetration, good clit access, good for me to tug on hubby's nipple rings...that really turns me on, good for kissing and seeing his face, good for looking down seeing him sliding in and out of me, and it's the best position for hitting my g-spot. Same position is my favorite for anal. I love to stand behind hubby while he's got a girl in doggy position...I love the way a woman's ass looks like that, absolutely beautiful!
Yes, Frisco, that's me in my avatar as always. That pic was from Sat. night at my friend's Mardi Gras party up in Mass. The full size is in my gallery. I got lots of beads!
