oooo good question!....
I love doggie, most of the time. It lets my SO get so deep and touch places he normally doesn't, and it feels SOOO GOOOD to be all stretched out with him inside me as deep as he can go. Plus it is good for those times when I'd like to be fucked like a dirty dirty slut.
Another good one is me lying on my back, left leg over his right shoulder, him kinda kneeling between my legs. That's good for some deep penetration, and we can look at each other.
Another favorite is him lying on his left side, me lying on my back with my legs thrown over his hip. It's not too strenuous, and it feels really, really, REALLY good! I must say that I've had my most intense orgasms ever from that position!
And you know, I think I agree with what Blackthorn said: any position with him with me and nekkid!
