Hi everyone. I (39M) posted here a while ago if you want some background. Anyway, things are settling down for my wife (38F) and I and we've talked A LOT. A girl that I plan on having sex with set my wife up with one of her friends. We are going to have a double date to get to know each other in person in a few weeks and fully expect to have sex that night if there are no surprises. We are all looking forward to it and know that it will be fun.

With that said I can't help but have some anxiety and nervous energy surrounding the date and sex. It's mostly from societal conditioning and from a politically conservative (though not religious) life outlook. I told her guy friend in our side chat that I compare it to standing in line to board a roller coaster with the nervous excitement and the "what if's".

The biggest question that I have been asking myself is why am I not only ok with my wife having sex with someone else, but encouraging it? I know the answer is that its something that we both want to happen, but I can't get over the fact that I genuinely don't mind and that's strange to me coming from such a long monogamous marriage. Can any of you who have been in similar circumstances share some wisdom on how you got over these last few roadbumps?
