I can't buy that watching porn is anything like cheating, nor is it wrong to masturbate. What it may be is a way of evading important issues. But cheating is taking it a step too far.
Sharing porn is an act of intimacy - perhaps not the kind you were looking for, but perhaps a start. The key is "sharing".
BTW, I suspect that shaming someone about something they want to do will just force him to hide it more, and I am not sure how that's a good thing at all. Accepting it and embracing it may just lead to some surprising responses. One of the things I take from Ms. Davis' books is that if you change your behaviour, your spouses will change too. Shaming your husband hasn't worked so far, why is it going to work now?
