to Peter1big1 :Same. If it seems to turn a guy on, I try to make my ring more prominent and wrap my left hand around his cock while I suck him to flaunt the fact that the throat he's pumping his cum down is married to a woman who's probably wondering where he is.
Likewise, I love watching my wife with another man, and it's a huge rush seeing her stroke with her left hand, so her wedding ring is pressed up against extramarital cock.
