I saw that there is a lot of different reason for people to want to expose their wives.
My wife absolutely hates being treated as an object. Once I bought her a small shirt where her stomach was visible. We went for a walk, and someone whistle at her. I liked it but she didn’t, and we had to turn around so she could change.
I would never post without her consent, so the humiliation theory is no good for me. I love her and respect her way too much to do this behind her back and I would probably loose her if I ever did, and she found out.
So why I want to show her off, well because I think she’s sexy as hell. Probably a bragging right to show what I’m making sweet love to. (I could say fucking but, trying to be more respectful 😊

So maybe the trophy wife may apply a bit. Also, I know I like to see other people’s wives so I would like to spread the joy with mine.
There may be some caudaulism, or maybe living through someone else. I have a voyeur and exhibitionist side and we know that being a man it’s just not the same. So having my wife doing it, it’s like living vicariously through her.
Finally, I just like her to dress sexy because I like looking at her and if your lucky enough to be around then enjoy. But having someone looking at her and being a little bit envious is something that I still like but I interfere when someone if trying to it on her because we don’t like it.
