In response to Toni who posted a comment on my previous blog post:
"So being poly is fucking whoever you want, good good I must be poly then but it seems my poly relationships are quite short-term. I know some of my past poly relationships have been with people who were in relationships with monogamous partners, but it would have been bad form for me to discourage their poly lifestyle, even though their husbands were probalbly unaware of the poly element in their relationship. I guess it is the responsibility of the poly partner in a monogamous relationship to inform her partner. It would be socially awkward for me to introduce myself as the fellow who is fucking his wife!"
At no point will I ever encourage someone who is poly to act in a dishonest way in their relationship/s. Cheating on your partner/s is always cheating regardless of whether you are poly or monogamous. You can cheat on your poly partners as easily as you can cheat when you are monogamous. I discourage all forms of cheating and instead encourage people who are tempted to cheat to sort out why they are tempted to and to talk to their partners about it or resolve the issue as they best possibly can. Counselling is always a good option.
To say that polyamory is fucking whoever you want is over simplifying the whole issue. Polyamory is ethical non-monogamy. If fucking whoever you want is indeed ethical to both you and the fuckee, then go for it. If it isn't, then perhaps you need to rethink your strategy and ideals and come up with something that is ethical.
I demand honesty from my partners and I give it in return. I would have big, insurmountable issues with a partner if they were not being honest with me, in fact that would be a deal breaker. Part of that honesty is ensuring that their partner is aware of me and ok with the relationship I have with them, whether that relationship lasts for a night or much longer.
