My husband works night shifts, so we have sex about 2 to 3 times per week. Today I caught him masturbating before taking a nap. I'm not sure how I feel, I have mixed feelings, including feeling unwanted, duty and ugly. We have 3 kids and I'm not in bad shape either. I know I'm attractive for other guys. The worst thing is that this is not that first time I have known about it. I found pictures of other girls on his phone, and porn sites as well. We spoked about this and it stopped for a while. I know he is not cheatting on me, but the fact that he is watching porn when I'm around and he knows I wouldn't mind helping him masturbate or have sex it hurts. He said he does it so it can help him fall asleep when he is not tired. Not sure what to think?
