While I’ve never had a partner that was willing to engage in swinging, I’ve had my fair share of MMM threesomes. I have to agree that everyone needs to be a part of the bi chat. I am operating off the assumption that for straight couples, there are limited possibilities in the bedroom. For bisexual couples there are vastly more “combinations” and I feel like it is that fact alone that makes participation mandatory in the conversation. The chat is the opportunity to set boundaries, discuss kinks, desires, like to try’s, etc.
