Why do some Men show off their Woman with revealing Clothing in Public?

Tonight I was at my favorite pizza joint. It's a family place in a nice suburban neighborhood.

A couple walks in and the young woman has shorts that reveals half her butt. She was with this guy, and they seemed chill.

Most of the people and guys like me were checking out her exposed bottom, and I studied the couple. After they ordered, they stood in front of everyone and this woman crossed her arms over her chest.

Her boyfriend gives her a funky stare and she began to reluctantly drop her arms down that revealed her boobs, nearly see through in a cheap white sports bra. You could see everything. No imagination was needed and she looked humiliated.

Everyone was checking her out, and many women in the pizzeria had very disapproving stares. And I noticed that her boyfriend was getting off.

I have heard stories from friends. Mostly guys who went out to a customer's home to install something and the husband asks the tech if he minds his wife to walk around topless or naked? Even asking sometimes what my tech friends thought about her body. Same thing as the couple tonight, with the man totally getting off showing his wife's body. Same wife reaction not too comfortable showing off, but going along with it.
