Every other man mingle to...

Anyone understand what this means?

My guess is that the OP is wondering why someone would have a relationship/affair with someone else after being in a healthy marriage.

If that's correct then my answer is that they wouldn't. People in a healthy marriage don't stray from one man/woman to the next, they are committed to each other. It's only in unhealthy relationships where infidelity/cheating occurs.

May be he means all Men here, no women.

Most prisons also fit that description...

Same reason people do pretty much anything.
To derive a perceived benefit, or to overcome a perceived deficiency.

People on a diet can eat a completely balanced and healthy meal, it doesn't mean they don't crave a piece of pie or greasy pizza. Some are better at denying themselves than others.

Pregnant women can be in the middle of eating a bowl of their favorite ice cream, and then go for a handful of pickles. Increased blood flow, some deficiency in her sodium or nutrition, can influence her craving for certain foods.

The reason people do anything: they want more, or they think they don't have enough.

It's outside the norm for people to accurately measure the value of what they actually have.

Too many implicit biases.

Some ppl just cheat . It is what it is
