I'm reading RotS novelization once more and this gem right here:
"Obi-Wan Kenobi opened his eyes to find himself staring at what he strongly suspected was Anakin's butt.
it looked like Anakin's butt - well, his pants, anyway - though it was thoroughly impossible for Obi-Wan to be certain, since he had never before had the occasion to examine Anakin's butt upside down. "
– Revenge of the Sith. Chapter 6
