There is quite a spectrum of this behavior in men.

Ranging from :

Watching another man have sex with your woman (Cuckholdry/hotwife) >> Enjoying your woman having an OnlyFans >> Wanting her to dress sexily in public >> Wanting her to dress modestly >> Controlling where she goes and who she sees >> Killing women so 'no one else can have them'

There are tons of more behaviors that fall somewhere in that range.

But what I want to know is: What causes these different behaviors in men?

For the men who like to share their woman/bask in the desirability of their woman, do they not mate guard? Do they feel jealousy but it is overwhelmed by a feeling of pride that they have the 'claim' to said woman? Do they consider her replaceable?

For the men who are against sharing their woman in every sense, are they trying to control what they see as an extension of themselves?

How is a man's woman being an object of desire by other men a form of pride for one man, yet for another man it is an attack on his pride?
