D&D 3e had a third party supplement called “The Book of Erotic Fantasy” which was simultaneously progressive and regressive at the time. YMMV, but you can probably find the PDF online easily enough.

Not the op but I felt like sharing.

I think monster hearts made some splashes because it has rules about sex. Never played it but it was one of the bigger pbta games.

My pandemic DND game had several rom com subplots, but everything was PG rated. The players got the tavern keeper shy man to finally ask out the Scary Strong blacksmith lady. Later, the self described “gay gay homosexual gay” player character had a whole Thing with a NB arcanist they met at a party. Lots of awkward uncertainty and innuendo. Very good time. Another player declined to pursue a romance subplot with an interested npc. All of that was fine. We didn’t use much systems for it because DND is very bad at that.

A game of vampire I ran pre pandemic had a PC exploring their relationship with a mortal woman. Their actions got the woman shot by their enemies , which caused the woman to Awaken as a mage. That story had legs. Minimal mechanics for it, but there weren’t a lot of conflicts to roll for with the relationships anyway. Sexual content was mostly off screen.

Hi! This is a really awesome question.

Giant wall of text incoming, but I am a Librarian and I have been trying to completely answer your question

So one of the reasons why I need this meme is because I wanna explore how we can be cool about things that we’re not expert that or do it all.

I have never role-played sex, or even romance very heavily. The most that ever happened was five minutes saying I made out with somebody and then fade to Black.

However, there was a whole range and continuum of erotic role-play from people who do it just to be titillating and hav like playing a sexually explicit game of cards against humanity. Two people who use it as foreplay who actually have sex at the table.

( that’s a really wide continuum)

There are several systems for erotic, role-playing, including rules for fifth edition.

Full disclosure, I received a copy of this from the publisher to review, but I genuinely enjoyed it.

Rolling for seduction.

So it adds three sexual skills to the game. Dominate submit, and generic sensuality.

There are sexual status effects, like desperate, and satisfied.

But what I really want to applaud, in highlight is the excellent game master advice.

Including safety tools, but also things that I wouldn’t expect like setting ground rules about thirsty textS.

Cool for people to like be trying to have sex with each other a hook up in real life?

Exactly house expose people want to be, would it be OK with masturbation at the table? For instance?

The only thing that makes that OK or not OK is a mutual agreement if everybody at the table.

And the thing is if you like the book publisher has several adventures and a erotic location guide.

For instance, there’s a Funhouse Dungeon and that is basically sex toy themed instead of traps, and the gladiatorial bring where they practice erotic combat.

Please let me know if I can help with anything else!
