Since then, Cara and Ashley have gone public, but one question remains: What on earth is sex bench?Ī sex bench is a BDSM tool for anyone interested in kinky sex play, anyone who’s physically impaired and struggles with comfort during sex in bed, or people who need a little extra help getting into the positions that optimize their pleasure, says Shawntres Parks, a licensed marriage and family therapist. Between furiously Googling for clues confirming Cara and Ashley were indeed an item and mining the internet for the definition of a sex bench, the photos kept fans well occupied. The then-rumored couple was spotted carrying a sex bench into their home, and it sent the internet into a frenzy. It's rare to get a peek into the sex lives of celebrities, but that's just what Cara Delevingne and Ashley Benson accidentally/on-purpose gave the world last June.
