1. Johnny and Gyro 100% had sex during the Steel Ball Run, likely after the Sugar Mountain Spring arc.
2. Hato Higashikata has a fansonly account.
3. Semi-canon, but Hirohiko Araki probably really likes being called Eroiko, the sometimes pronunciation of his name in France and Italy, which translates to "erotic young man" in Japanese.
4. Diavolo had a pregnancy fetish, up until the point he actually got Donatella Una pregnant.
5. Despite being labeled as one of the most perverse characters in all of JoJo, Melone has never actually had penetrative sex, and is more into tantra, kama sutra, and various kinks.
6. Ermes Costello offscreen is an dominatrix for cash while in Green Dolphin St. Prison, but only takes female subs.
7. Ringo Roadagain has a primal hunter fetish, or the act of being sexually aroused when hunting another person through scenario or not.
8. Of all the JoJos, Jolyne has done the most sexual experimentation. That might not even be a headcanon, considering her personality.
9. Lisa Lisa was a mainstay at Hollywood swinger parties after Battle Tendency, but halted the practice after marrying the screenwriter, whom she met at a party.
10. Most people accept the fact that DIO and Pucci have a physical relationship. What I posit is that DIO also had sex with Vanilla Ice, Mariah, and Midler.
