Every bi cis woman who is married or a long-term relationship with a cis man that I've tried giving the benefit of a doubt and dated or chatted with on a dating app has suddenly had to stop seeing or talking to me when the man they're with gets insecure and expresses "a boundary" that she can't do anything physical with another person or meet up with them. Like...bi ladies, leave your insecure, sexist man and go kiss girls already. A man controlling your body is a man controlling your body and should be kicked in the balls and left to be lonely and butt hurt by himself. ARGH.
To be clear, it is absolutely understandable that when people start venturing into non-monogamy, they may need to take things step by step, or even stop for a time. But a boundary is not "you can't do X," a boundary is "if you do X, I'll do Y." That's not a boundary and not a way to do non-monogamy or polyamory!!!
