New Couple Wondering Where to Start (M31+F27)

Hello!

We are a couple that has been wanting to explore with other people sexually. We have had many discussions and fantasies about bringing in other people and then moving towards each other doing hookups alone. After the alone sessions we have both agreed to come back after to have sex with each other while describing everything.

We have had an infinite amount of conversations about communication and trust and how it would work. We both are very into this but cannot seem to figure out where to start or how to go about bringing other people in. Other socials like snapchat or dating apps seem to be lacking with people realizing they would be a third or not into sharing their partner while we share ours.

Any good ways to start trying to meet other people with similar interests? Looking up things always points to these "have flamingos and upside down pineapples everywhere" and no people actually discussing how they started.

Any help would be great and we can answer any questions about what we want or to clarify anything!
