I had to hop out of the lurker bushes on this one.
You, my friend, are purposely (perhaps not maliciously) misleading women in the attempt to lure them in. As someone who has failed countless times when seeking a secondary, the fact is that most women will side-eye you, then turn in the other direction when you disclose that you are in fact, polyamorous.
This in mind, I'm sure you've experienced it as well, and have chosen this route as your loophole to the process. Unfortunately, it's based on deception and slight of hand and will gain you nothing except a guilty conscience, bitter pseudo/could have been secondaries, and a terrible reputation.
Sorry, but you probably need to be more willing to fail with the truth.. or at least most of it upfront, than failing in the long run via misdirection/smoke and mirrors.
