When facing your lover in bed, place on leg on top of another, another top of that, and the last on top of all three. The leg sandwich essentially allows for a more comfortable frontward-spooning and puts the aforementioned awkward appendages to better use.
If my husband and I don't leg sandwich while laying in bed, his fat belly gets so much in the way that I can't kiss him and I get spinal deformities when I have to arch my back so far up just to reach his face.
