“I am promiscuous because I am curious,” reads an introduction to Soulmates: A History of Our Fetish for Feet,” a book authored by Adam Zmith, a writer and podcast producer whose work focuses on sex, queer identity, LGBTQ+ lives, history, art and desire. In my Smart Sex, Smart Love podcast, Zmith shares that fetishes with feet are a centuries’ old pleasure that most cultural groups have explored. In fact, one in 6 people have fantasized about feet, and it is one of the most googled fetishes. It is a whole universe of pleasure, he has discovered. In my podcast, Zmith also talks about another book he wrote, Deep Sniff: A History of Poppers and Queer Futures, a “manifesto to pleasure,” he describes. Through his work, including a weekly podcast entitled, Free Sex, Zmith’s goal is to build a world where everyone can have sex the way they want it.
