For some reason I never did think of this as something to be ashamed of, but more like something I was just proud of instead!
I can't tell you how many times I would invite or have friends / co-workers / other neighbors and even some distant family members come over to our house and never got to see it before but would ask if I didn't mind giving them a tour of it!
I had a few guys over the house and help me with working on some Street Rod cars that we were restoring, but never seen anything but the garage!
On a few occasions my wife would be home and maybe follow us along as I showed off the entire house.
But the main Interest to all of them, so much that they at another time would bring their wife / GF over for a tour too was out main master bedroom!
When your living in the house there are many things that just get normal or routine to you and it just slips your mind for the moment, but others catch it and really take notice~!
The huge studio blown up pics of my wife NUDE and exposed showing all of her natural glory~
We even had a few of her doing oral with a stunning look on her pretty face in more of a close up, but the cocks she was enjoy weren't mine!

I think the reason many of the guys for bring back their wife / GF, was mostly to show them what others do that have a sexual lifestyle!
I can also say it is a nice way of introducing others into the same adult pleasures and maybe having them join in at sometime too!
Maybe others had this happen too and thought it was either something to be ashamed or proud off at the same time!
