Math is surprisingly not about math! This soft-cover books feature sexually explicit artwork and writing for an increasingly connected and liberated world. Each edition represents a diverse range of perspectives and aesthetics. And every page is a celebration of the full spectrum of sexualities, genders, and body types. Enjoy reading alone or with a lover and see how Math inspires you to live your best sex life! Math #9 is the project’s biggest and most beautiful edition yet! The cover features a holographic foil and inside you’ll find 200+ pages of unique, hot, and inclusive sexually explicit media. Not to mention the centerfold and an extra nerdy fold-out.
