When people get too sexual while playing DnD. I don't care if ur a bard, if u try to push my beautiful autistic DM into describing ur fantasy I'll kill you in ur sleep.
Was almost gonna play DnD but then found out the group essentially used it to write smut together. So essentially they'd spend the night role playing characters flirting with and fucking each other. Feels like they should probably just fuck each other.
My current rpg (playing Fate and not D&D, but still) has two clear rules from session 0: No foregrounded sex, no foregrounded gore. I also did a "And let's move on" when one of the players was trying to flirt his way into a bar.
