STI… but the problems with people cheating are present in polycules or any other relationship…
people lie and cheat….

i’m not saying they’re completely bad and nobody should ever do it (sorry downvoters, you have my blessings), it’s just the kind of thing that concerns me in these scenarios….

afaik, people tend to do things like get herpes, not tell anyone, and tell people it’s not even worth tripping over… just a lil herpes…

and as long as your polycule isn’t a closed loop, it’s essentially infinitely large….
