A friend of my recently started her first poly relationship. Several weeks into it she found out he was messing around with her sister.
She asked him to not do that again. "Why not," he asked. "We agreed we could be with other people." He was honestly baffeled as to why this crossed a line for her and told her she was doing poly wrong. No, she wasn't. He was. And, as he deserved, was promptly kicked to the curb. All of this is a way of saying that just because you are poly does not mean you can ignore or scoff at reasonable limits your partner may have. That is all.

Me: The thing is you are more punk than I am so why not go for it? Rome Girl: I am so not punk. Me: You spent your childhood on tour, dated an ex convict for seven years and have dated an illegal alient expat for ten years whle helping him break the law. Yep. you are not punk at all. Rome Girl: well, when you put it like that.... LOL
