I often enjoy watching porn and masturbating on my own time. However, I sometimes feel guilty about this because my wife doesn't know and I don't think she'd be happy to find out that I was doing this. She is an active member of the mormon (LDS) church. I used to be, but am no longer active. In the past, I didn't feel guilty about masturbating and watching porn because I actually felt like it increased my performance sexually. But now I feel like it may actually be making things worse.
I was actually thinking about telling her about one fantasy that I've had which is to watch an erotic video or porn with her together. To masturbate ourselves and each other while watching it. We could find something that was ethical and watch it together. I think this would help her to see the value and excitement in doing this sometimes.
