Willy Wonka And The Polyamory Factory

Here’s a common mistake I see among newbie poly couples: Charlie has just gotten a Golden Ticket to see Willy Wonka’s Magical Chocolate Factory, which in this case is defined as “the really cute girl who does all of the freaky things that his current partner is not interested in.”
And the partner says this:
“Yes!  I’m so glad!  You can totally go to the factory!  Just… don’t eat the caramel.  And if he wants to show you the room where he beats the chocolate, don’t eat the grass.  Or the candy flowers.  And don’t go in the tunnel, I’m not cool with that.  And if he wants to give you the factory, that’s crazy responsibility, say no.”
Now, it could be argued that hey, at least this way Charlie gets to see some of the factory – but realistically, he’s going to spend so much time worrying about whether he’s going to partner his wife off if he hugs an Oompa-Loompa that honestly, he’s going to either hate the factory or hate her.
(Obligatory note: this is not gender-specific, Charlie could be a woman, overprotective spouses come in all genders, thankyouverymuch.)
What’s usually happening when you get the Great Golden Ticket Disclaimers is that the wife doesn’t want to tell her husband, “No, you can’t go to the factory” because she knows Charlie is actually Augustus Gloop and he’s going to fall in the damn candy river.  But she doesn’t want to say that, because then she’ll be a Bad Poly Partner and Charlie will be all mad… so instead, she comes up with a list of a few, uh, provisos, a couple of quid pro quos, until she’s essentially walled off all the best parts of the candy factory.
And you know what?
Charlie usually falls in the damn candy river anyway.
Sex/love/affection has an uncanny way of seeping around protective clauses.  The goal with a a poly relationship should be to find someone everyone is comfortable with, not to take someone and rules-lawyer them into a semi-acceptable form.  If you have to do that much work to make the candy factory safe to travel through, then you should just condemn the fucker and not let Charlie go.
And Charlie will be mad.  Charlie may actually be pretty stupid, because people tend not to learn from reading essays or being given advice by friends.  No, people learn from grabbing the special Three-Course-Dinner gum off the table and cramming it in their mouth and blowing up into a big purple mess when the dessert portion doesn’t work quite right, and only after they’re squooshed back down into somewhat normal size by Willy Wonka’s extremely painful machines do they say, “Wow, I probably should listen to Willy Wonka when he tells me no!”
Which leaves you with an uncomfortable choice, when the Golden Ticket appears: do you say “no,” and let them seethe for the rest of their lives about what a gloriously perfect experience the Chocolate Factory would have been… or do you let them go, watch them fall in the chocolate river, and hope they learn? Or do you let them go and discover that indeed your partner is Charlie Bucket, and gets the factory, and deal with the stress of being a lucrative candy magnate?
There’s never a good answer there.  And I’m not saying, though people will doubtlessly misinterpret me, that restrictions are bad.  (“Safe sex” is a pretty darned good restriction, f’rex.)   What I am saying is that raising fifty million provisos because you’re too afraid to say “no” is often way more harmful than the flat “no” – because if, by some magnificent chance, Charlie follows all your guidelines and emerges from the candy factory whole, chances are good he won’t think, “Wow, all those guidelines protected me from danger!”  He’ll think, “I could have had so much more fun if I wasn’t held back by all these stupid rules!”
But it really is okay to say “no.”  It’s tough, when those golden gates are opening.  You may even find Charlie running off, alone.  But if you never wanted to own a candy factory, or deal with the unique form of PTSD one only gets when you’ve been sucked through the garbage chutes of a chocolate factory and are barely saved from the incinerator, then maybe letting him go off is the wiser choice.
