If your RPG game has sex scenes it should have skill checks as a part of those sex scenes. Let me fail my roles and do bizarre and comedic shit! Let me bungle my charisma roll and say some deeply strange and unsexy shit, let my character slip and fall mid scene, let my character simply stare at somebodies genitals while slowly formulating a plan of attack, let them bust out their deeply unimpressive “secret technique”, let the get distracted and stop midway through because they need to check something.
I don’t want to watch your perfectly crafted and extremely sensual sex scene, I want to play the game!
Bard: I seduce the chambermaid.
DM: Okay, roll charisma.
Bard: *rolls a 1*
DM: Mid-sentence, you fart loudly. It echoes down the hall. The tavern cook sticks his head in. “Enjoyed my beans, did you?” he says.
Bard: I also seduce the cook.
DM: *sighs* Roll charisma.
Bard: *rolls a 20*
Cook: Luckily for you, I do enjoy beans
