Are you gay? Are you male? Are you straight? Are you female? These aren't necessarily questions with yes/no answers. Gender and sexuality aren't black and white, binary concepts - they can be fluid, and are often on a spectrum: 40% of people under 25 don't identify as gay or straight. Society hasn't necessary caught up with this, though, as comedian Mae Martin notes in this hilarious look at sexuality, dating and gender in the 21st century. She notes, partly in humour, partly in frustration, that it's 2017, and we are still labeling people by who they sleep with. Expanding on themes raised in her BBC Radio 4 show Mae Martin's Guide to 21st Century Sexuality, she aims to break down barriers and start conversations. With a blend of personal anecdotes and clever social observations, Mae gently pokes fun at stereotypes, pigeon-holing and intolerance in this truly millennial book.
