Why are guys in the military/ navy such assholes?

Just recently broke up with a guy who was in the military, before I went out with him a bunch of my friends told me not to date men in that field because most of them end up being liars, cheater and sex addicts and I didn't believe her until I dated one myself.

So why do you think this is? And yes there are SOME exceptions
