I was so sad to hear of Jack Morin’s passing. He was a true innovator and the author of two of the most important books on sexuality: Anal Pleasure and Health and The Erotic Mind. When I found out that Morin was dying, I wrote him this letter. I am sharing it here to celebrate his amazing life.

Dear Jack,

There really aren’t enough words to describe just how important your work in the field of sexuality is, but words are all I’ve got, so that’s what I’ll go with. I feel like none of my work could exist without yours. When it comes to anal sex and anal health education, obviously, you wrote the book. But it goes far beyond that: you broke the ground, you blazed the trail, you opened up the discussion, and you boldly put your name on all of it at a time when no one was talking about this taboo subject. By doing so, you made so many things possible. Anal Pleasure and Health has a pivotal place in the history of sexuality and sex education in the last century, and I am forever grateful that you wrote it. I still have my copy of what I think is the first or second edition, the one I read in the early nineties, with its dented baby blue cover and pages all marked up. I was interviewed last month for a full page article in Glamour magazine about anal sex, and that’s just one example of the tremendous cultural shift that’s happened in the dialogue about anal pleasure. You made that happen, basically. It all comes back to you. You made it possible for my book—and countless other books, articles, websites, videos, and workshops that discuss anal sex—to exist.

You’ve left a legacy of shame-free, sex-positive, holistic, pioneering work on anal pleasure. It inspired me to write my book. And I know it has inspired thousands and thousands of people to explore anal pleasure in their lives. And that’s just one of so many things you’ve done in your career. You are a leader and a light in the field of sex education. From the bottom of my heart, I want to express my gratitude, my respect, and my awe for everything you’ve done to make this world a better place. I promise to honor you by taking the torch you lit and setting the motherfucking world on fire. I’ll do my best, anyway.
