Your S.O watches to much porn?

How would you ladies react if your s.o watches porn almost everyday. Its either porn site or on YouTube watching girls shake their ass. When im on my period I dont mind cuz sex is furthest from my mind. But when he looks at that stuff instead of approaching me for fun time, it makes me feel low and unattractive. Ive told him this before and times he does stop, (I check his history). But then when I catch him he gets mad and says he needs his privacy or hes just a man that he just wants a quick "bust" or release at times. It bothers me a lot but hes not getting it. How would you ladies feel or think on this situation?
