Is it too much to ask that i be allowed to listen on the phone? iin?

My wife has dated outside of our marriage for about 10 years. It started with threesomes and spouse swapping. It developed into the wife hooking up without my presence. It has now evolved where the wife has had a steady boyfriend (black, with a much larger penis than my white one) for the last 3 years. On rare occasions I have watched and particpated, maybe 6 times over 3 years. It is still exciting hearing the details, but some of the excitement has waned over time. I have asked my wife if she could call me on her phone and just let me listen every once in a while. Her response has been that her boyfriend isn't cool with it, feels weirded out knowing I'm listening. I'm feeling left out in the cold, am I being unreasonable?
