Mmm.. ok, one that worked for us...

you lay on your back and he lies on his side - but your butt is against his... doodle.. and your legs are over his back and upper thighs.. does that make sense? So if anyone walked in the room, they would see you guys trying to make the shape of a mm..well I guess its sorta like two bookends pushed together??? takes up a lot of room on the bed so I hope you have at least a queen size bed!!! lol

Works well though - more penetration than missionary (if you can angle it the right way) but not as much as doggy..

Good luck!
