Even if you are liberal anglo Aussie male and your son ends up having sex with your wife, it have potential to turn nasty.
Granted.
People have affairs.
Open relationships.
Swingers parties.
Orgies & Sex parties in their living rooms & backyards.
Cuckold relationships, where husbands like to see their wives with other men.
It all goes on & is across wide demographics.
Teachers, Doctors, Nurse's, Legal professionals the list is broad.
Other family members don't know about this "Lifestyle", nor do the general public and friends.
It's not in FB profiles, but it exists.
Only a few outside the circle could name the participants, and personally, up come up with about 14 couples locally.
(Covering those professions mentioned above, plus a few more & all upper class people).
No one "Outs" them, like was the fear of the Gay community years ago.
But if the pastime WAS to come out amidst the close circle of family & friends there would be outrageous results.
This is worth reading rather than dismissing.....
