>>251953Back in 3.5 ed. before WotC became a bunch of shit heads, there was a third party rule book for sex that was published called the Book of Erotic Fantasy. You can find some homebrew updated versions of those rules for 5th ed. floating around the internet if you want. But honestly its extremely unlikely you'll ever play with a group that won't just fade to black. Honestly only some sort of DnD nerd swingers party would be down for it.
