Let's hear from guys & gals, lers & lees. Unfortunately, I don't have any first-hand experience with this although I have read plenty of commentaries from women who enjoy how sensitive guys get after orgasm.
I once read a very explicit interview with a Playboy model, who said her favorite thing was tying guys up for very long oral teasing sessions she could completely control. She specifically said she enjoyed how they could not interfere with her post-orgasm teasing. She even gagged them so as not to be distracted at all.
