In setting out to write Future Sex, Emily Witt 

I hoped to define what she once considered an “interim state”: the sexual identity of being a single woman unconstrained by long-term reciprocated love and partnership. The language used to describe relationship statuses within this state, such as the too all-encompassing “dating” and outdated “lovers,” she argues, has lost its meaning in the 21st century. This leads her to another query—perhaps this state isn’t so interim after all
