Why do people feel the need to 'show off' their daughters for cheap sexual gratification points from others ?

I find it a bit creepy that anyone would show off their daughters to gain sexual gratification attraction interest from others?

A guy at my work (70) kept trying to show everyone nude and semi-nude pics of his adult daughters. He lost his job after touching a female employee on the ass and refusing to apologise for his actions or show any care/concern for the other person and the rest of the workplace cohort.
