Tinysex, or TS, is the roleplaying of sex or sexual situations of any kind. As Persona MUSH runs on a rating of M, we do not enforce a ban on TS, though the baseline preference at which you should operate is for the scene to fade to black. Anything more explicit must be agreed to by both (all) parties. Additionally, please obey any and all relevant laws in your local jurisdiction.
Any scenes of this nature must be kept private, for the convenience of those who do not want to see it. TSing somewhere you can be readily seen is grounds for a strike against you, and also for the immediate and eternal ridicule of the entire game.
