My first pop-culture encounter with tantric sex was—like so many other “edgy” sexual practices, from threesomes to fetishes—during a “SATC” episode. The women attend a tantric sex workshop in which a white-haired woman massages her elderly, blissed-out husband, who, after some buildup, ejaculates into the air and … onto Miranda. Educational? Sure. An accurate depiction of tantra? Not so much, according to my sources.
