If he asked to review he never got the impression he didn't satisfy you.
Next time something like this happens during the proper massage of the HE, you should make suggestion about how to improve your experience at the moment and not after. "Room, oil, temperature."
Reminds me of guys who later complained they didn't like the lubricant or the escort had bad breath but they never said a word when it matter and would have made a choice.
Just my 2 cents.
