My wife(25) and I(28) have developed a situationship (the best way I can explain it) with another married couple close to us. Everything is going swimmingly as a group. We have talked as a group, as couples, and 1 on 1 with our extramarital partner. We do all of our communication with the extramarital partner over Snapchat and have all messages saved just in case any party wants to read anything said. We also have a group chat on Snapchat to allow us to talk real quick on things, bullshit, or just put a stop to any communication if need be. I feel like the communication across all parties is really good. Everybody respects everybody's boundaries and needs. Now down to why i'm posting. For some reason this past week i've been getting anxiety around things that we have been doing for months that haven't bothered me at all. I have zero clue why. My wife and I have talked about this and we discussed that we both enjoy them as friends and anything sexual is out of nothing but lust and zero romantic feelings. Which I think is completely fair. I don't feel as if i'm going to lose my wife to another man, or anything along those lines. I'm happy she enjoys her time with him and they have things in common that my wife and I don't. So she gets to do things that her and I typically wouldn't do. When it comes to sex. We either have sex as a group or 1 on 1 with our extramarital partner at our different houses at the same time. Multiple times myself and the other man have swapped houses for a couple hours then we go back home. Nobody is being left out as we all agree none of us enjoy being left out. So how can I navigate feeling anxiety over these things when while i'm feeling anxious i'm doing the exact same things i'm feeling anxious over. Thanks in advance!
