How do you feel about...

How do you feel about pornography? How about your SO masturbating to porn? If you don't mind porn, do you care to explain why it does not bother you? For me I have never liked porn but I also have never had a "real" reason besides it degrades women and the best I could think of, especially when it became a problem between my SO and myself, is that I do not like my SO looking at other naked women while doing an 'intimate' thing, as I have always seen masturbating as. It bothers me for him to lie next to me, asleep or awake, and masturbate to other naked women. Maybe it is insecurity or jealousy, I'm not sure, but I wanted to see what others thought.
