Why do guys hate when we have male friends because when I ask my boyfriend he gets upset he ignores my question?

Like i set boundaries to my guy friends who both are in a relationship but i always keep them at arms length yes we joke around but its never to the point we get touchy with each other i try to ask him what upsets him but he again gets mad and on my end i want to know what upsets him so i can do better on my end or try to avoid doing what gets him mad.
