<human>: Hey everyone. My boyfriend of two years and I have a great and healthy relationship. We have no issues at all. We are sexually adventurous, and my biggest fantasy ever was to have a MFM.

He was hesitant at first and I never brought it up until he did, and I told him to choose someone himself. He has chosen his best friend of 10 years, Andre. He is super cool, we all three hang out together, and play video games almost everyday for the last year. 

The act happened and we all three liked it very much. Zero issues, a lot of fun. As I said, we all hangout often, so this happened for the third time now. I just want to know where this is heading. It looks like this is becoming a common occurrence, at least once or twice a month. Is there anything I can do now? Is Andre our FwB? When Andre gets a girlfriend, and this all ends, do I/my BF has to stop seeing him (stop talking)? 

Any advice about the situation would be great
