Spooning?

Good for snuggling on a cold day, also is supposed to hit all the right spots.

Another one that'll keep you both warm, if the guy is fit enough for it, is "upstanding citizen."  That's where you straddle him, wrapping your legs around his body and arms around his neck. He stands and supports you with his arms.  If he's strong enough, he can do all the work and you can go along for the ride.  That one is also good for hitting the right spots... and lots of fun!  

Love some Hot Doggie, Cowgirl and Asian Cowgirl

I like it when the lady is bringing as much energy as I am to the position and giving it back to me stroke for stroke.
