All the time with my ex-husband, it was the only way to get him off of me.
With my current husband, never. Out of all the promises that get broken in the course of a relationship, that is one that has survived. If I don't have an orgasm, then I don't fake it.
With my hand on my heart, I have never faked an organasm, in public. In a private chat room yes, usually because the phone rang. To the lucky ladies that know me, they can tell how intensive an organasm I have. Takes a lot of cordination, one hand up and down, the other down and up on the key board. Bit like rubbing your tummy, and head at the same time. I have invented an organamic arouser so that both hands are kept free, please send postal orders or money orders to the value of £20.00.
