"1) it's fake and can sometimes lead to unrealistic expectations and"

Replace the word "sometimes" with the word "rarely" and I will agree with you.

"2) it can be highly addictive."

Again, the proper word is "rarely". Over 90% of men look at porn and very, very, very few of them would meet even a loose definition of addiction.

"The man hides, you are very right, because he knows his wife wouldn't like it. And knowing that, he shouldn't have done it. "

I think it is entirely unfair to tell a man that he must cater to his wife's feelings no matter how absurd they might be. Honestly, does getting married mean giving up any individuality? Does a husband have to ask himself "would my wife let me do it" before making any decision?

"Should she be sympathetic to his horniness? sure; just because she's on pelvic rest doesn't mean he is - this is something we females forget sometimes - there is nothing wrong, in this instance, with her helping him out"

Why does she have to be involved in his personal activities? This isn't about her, it's his own private activity. Why can't she leave him alone once in a while?
