I can see how looking at porn behind your wife's back would upset her.

Opinions vary, but if looking at porn is infidelity at all, it's got to be considered the least of all infidelity-related offenses.

Direct her here, and let her read some of the horror stories. I'll tell her my story, for that matter.

After that, she just might have a different outlook on your porn viewing. She might even consider herself lucky.
