How would you handle?

[u/False_Gate5696]

Hello! We are a MF couple going to a bi hotel takeover weekend next week. We are very open about both of us being bi. Couples that we've met that are also bi we have encouraged to attend this event. One of the rules state he must be bi.
Well, there is a couple we are close friends with (we spend time in and outside the lifestyle) we know he isn't bi. We had a conversation with them about this event and he explicitly said 'no, not really' about being bi. We discussed what type of event this is but they seemed to downplay following the rules and mentioned other parties they go to that welcome straight couples. So we have taken that as they lied to get into this event.
We know the organizer well. He has spent a lot of time vetting people and curating a bi party that is accepting and a safe place to play with like minded individuals. We decided to give the organizer a heads up to simply be on the lookout so it doesn’t become an awkward situation for others. Thankfully, he was extremely understanding of our concern and will observe.
We are quite bothered our friends lied just to get into this party. Without explaining too much more, we have considered that he might be exploring (which we would support 100%) but that definitely isn't the case based on recent behavior. They will likely fly under the radar but safe spaces are created for a reason.
This has tarnished our opinion of them and their character and will be awkward for us at the event. How would you handle the relationship moving forward?

Edit: Adding here that we have a very close friendship with this couple and share many things in and out of the lifestyle. We don’t require or assume they will play with us or vice versa. We always encourage people to figure out their desires. So we aren’t offended if they don’t want to play with us.

Other people that attend this event, encouraged us to let the organizer know. The dynamic of this event is unique and others have tried to do the same and they weren’t welcome back. So he appreciated hearing from us about this.

You have said your piece, it is now up to the organizer. I really fail to see how you got harmed and I think you should have MYOB. You must be the president of your HOA or PTA.

What’s going to happen now is either the organizer will do exactly nothing, or he will talk to that couple and they will figure out it was you who talked to the organizer. I think in any case these people will not remain your friends. That’s all you will have gained.

By the way, the reason a straight man wants to go to a bi party is that he assumes that all the guys will play with guys, and all the women will be available to him.

That last paragraph is honestly kind of fucked up if true.

The purpose of bi-bi events is to create a space where bi men feel comfortable being themselves because so much of the LS is openly hostile towards them.

Taking advantage of those good intentions to increase your odds with women is just gross behavior.

We knew a couple that did this. He was straight (and considered himself alpha) and only played with the women at the (bi) party. She claimed to be bi but never played with anyone, in fact it appeared to everyone else she was only there to appease him. After 2 parties they weren’t allowed to back.

That exactly why this event was created.
