I'm lazy, so whenever the WG asks how would you like it. I'm like cowgirl or reverse cowgirl please. The larger / older wgs though I find try and make excuses like, my back hurts etc
To all intents & purposes, my disability limits me to these positions. "Ah, the lazy man's position.", as I remember one SP saying as I invited her to climb on board during what, by that remark, she ensured was my first and last visit to her.
I find RCG is marginally more comfortable for me but I can put up with😉 CG when the SP is fair of face/ample of bosom, or, preferably, both!

Oh, @Chatte Noir; "Neither of the above."
