Interesting concept and although thousands of couples live the lifestyle I should think very few if any openly live it so their intimate family know, maybe some adult offspring pick up the knowledge or vibes but that's it, more common is for the parents to know, personally my Mother knew I was a feminized sissy cuckold and had no problems with my second wife Tania having lovers, in fact they were a good Mother and daughter in law act and used to go shopping together having lunch with all the gossip so my ears were red often.
