I can dimly remember the last time I screamed out, "Oh, Mr. So and So!" during an orgasm . . . as I recall, in addition to the $100, he tipped me an extra $25.
Either that or it was in a previous lifetime. I never referred to my husband, lord and master by anything but Mr. Whoever.
I might be formal on brief acquaintance, but surely by the time someone is within orgasm range, I've moved to a first name basis. Sheesh.
