Why do people sexually insult each other or insult each other with sex?

Like why do many people insult others with prerogative words or sayings. Like sometimes guys in particularly will say something like "suck a dick" or "lick my balls" or some other thing in a derogative manner, usually when they get pissed at someone. And make perverse jokes about sexuality and even say they would bang you (as in a way of joking about homosexuality) and other such perverted nonsense they heap up in their minds.  And the weird thing about this, is that it's only ever guys that insult each other with sex like this. Like I never have witnessed a girl use sex as an insult. Why do dudes do this to each other. Are many guys really just this immature and just like to twist sex into this act that is like its completely abominable. Or is it because these gentlemen aka., "children" view sex as a display of power?

Please tell me about these puerile choice of words being a reasoning as an insult.
