Recently a few of the more overtly horny things for 5e have come to fruition on the patreon!

Nymphborn, children of a mortal and a nymph from greek mythology, whose beauty is so great that nudity makes them difficult to strike in combat. Featuring 14 different subraces based on the type of nymph parentage the character has. And a table of fun (and fetishy) quirks that reflect the character's ties to supernatural forces.

Litu, offspring ritually created by incubi or succubi to harvest sexual energy for the world. They're horny 24/7 but can't get off without temporarily stealing someone else's ability to do so.

Dathmorri, pulp and folklore inspired variant humans who categorically reject any type of clothing, armor, or privacy, live in tree houses, and master the art of tattooing and steelsmithing. Perfect for the "naked barbarian" archetype.

And of course, if you're going to be running a lewd TTRPG game in any system, you might want consent checklists for the sexy stuff that gets into a little more depth, like these [Here]

If you like this horny-ass stuff and want to see more of it, contributing to my Patreon [Here] will help it happen!
