i believe it affects really the sex life married couples if men had chance to look at the bodies of other beautiful young woman then he will see all the wrinkles and sagging of skin of his wife it is already enough for men looking at all these actresses and comparing them to their wives and then they ask why woman is doing plastic surgries?so that she can cope and live up to the standards of her husband,i believe watching porno alone is kind of cheating how in earth any man will accept his wife looking at a porn movie and watch the private parts of another men,if you do not agree then woman too do not agree that you this ,and if you agree then excuse me YOU ARE NOT A MAN NOT A MAN NOT A MAN,yes your woman should only fantasize about you see the privates parts of you and no one else, and the same goes for men,my friend her husband was watching porn with his laptop and she was in the same room watching tv,he entered the toilet and his wife checked then the laptop because he did not close it properly because of the urge to urinate that came with watching porn,she saw what he was watching so controlled her self did not say a word,later asked him to accompany her to bed on their regular time he said he is not yet sleepy and that she can go ahead and sleep she went to the room and waited 20 min and went back to the living room the door was closed but not locked as there is no lock to that door she opened it and he was mas.....ng she was shocked and had nervous break down as he was not having sex with her for a month since he bought his laptop,ok they are divorced now,GUYS THIS IS CHEATING DO NOT GIVE IT OTHER NAMES
