PositiveThe Washington PostWitt bravely plays guinea pig, taking readers inside sexual subcultures without pre-judging or snarking at them ... Witt treats her subjects (even her bad Internet dates) with respect instead of the judgment or mockery you might expect. It’s like reading something by David McCullough if he wrote about dating apps ... Many of the essays in Future Sex have been published previously, and they struggle to come together in a seamless narrative arc. Still, Witt should be applauded for avoiding the trap of self-absorption and for expanding our knowledge of sexual culture.
