Who We Are

Lee is D.J.’s little brother, so growing up he got lots of hand-me-down porn to help him grow his sexual understanding.
D.J. and Marc were roommates in college.

At school D.J. taught Marc his first words in Hebrew: “Tochlee et ha betsim shelli” (Translation: Eat my balls). Marc used that phrase on his first date with Anat and it worked. She didn’t eat his balls but she thought he was funny and they all lived happily ever after. Writing a sex book together just seemed to fit the natural progression for everyone.

  • D.J. Gugenheim

    D.J. Gugenheim grew up in New York, Israel and Florida. At 16, he moved to LA by himself to pursue a girl, which needless to say didn’t go well – if only he knew then what he knows now about Sexual Fitness. Despite this itinerant lifestyle, he was admitted to UCLA a year early and studied theater and business. There, he won the Gilbert Cates award for outstanding production. He worked at the Woodrow Wilson Center and on Capitol Hill. He worked for the filmmaker Joel Zwick (MY BIG FAT GREEK WEDDING) and used that experience to produce a short film with Kenan Thompson (SNL). Following that, he worked at CAA, Paramount Vantage and the Universal–based production company responsible for the BOURNE IDENTITY franchise. He runs production and development for the indie film company behind THE KIDS ARE ALRIGHT, THE GREY, KILLING THEM SOFTLY and GRACE OF MONACO.

    Throughout his quest to tell great stories and enjoy life and love, it became apparent to him that everyone could feel better and be happier if they had more sex and more exercise and so he decided to find the right partners to share with people a simple and fun way to engage in Sexual Fitness.


    “I used to pull my groin during a hard workout, now I have people who do that for me.”
