I prefer it with my OH (H) on top, and me (C) on the bottom, she is amazing at oral and in that postion I can cum very hard.
But thats not to say when where in the mood we dont do the others.
On ones that have been missed, me and the OH often use this website for new postions /www.sexinfo101.com.
They have 9 postions in the 69 family. http://www.sexinfo101.com/69position.shtml?s=7451c5b9c7b2f1e716d936d72eeb903c
Have a look, i think we will be trying http://www.sexinfo101.com/faceoff.shtml
"Starting upright in a semi-squat position, the standing partner bends at the waist, and touches down to the ground with their hands, carefully bending the head back between their legs to orally receive their lover's penis. Don't forget to bend your knees; this will alleviate strain at the joints. The receiving partner is seated on the ground with their legs fully extended in front of them."
