user7141: We all know the limits of a married person.We all know the definition of cheating in Buddhism.
But Buddhism existed in a time Porn did not exist.
So if a married person watch porn is it cheating?

user16515: Porn conflicts with Buddhism on several levels. One of the most basic defilements in buddhism (unwholesome roots) is greed. This is a self centered desire for pleasure or possession it also stimulates another unwholesome root in Delusion. Also if we are mindful of the topic of porn, we see the the porn industry exploits people for money and has been known to be involved in drugs and sex trafficking...
When you watch porn in marriage you are deceiving your partner for self gratification..
Porn contradicts the path..

user3597: Donating porn/nude arts, women to men for evil purposes, bulls for cows to breed, alcohol and arranging dances(probably sexually arousing) are considered evil charity which are sinful. So clearly porn is not something good but sinful whether or not it falls under physically cheating.

user8157: Some socially 'Islamic' people (as distinct from Muslim practitioners) get married on a Friday and divorce on the Monday just so they can have sex on the weekend & not break the rules. Obviously, this does not conform with the true spirit of the religion. 
Similarly, regardless of whether a person is married, delighting in pornography is an expression (for men) of the mind's view ('ditthi') about women, human relationships &/or sex. 
The scriptures state a wise man looks upon every woman like a mother, sister or daughter. For example, in a traditional marriage, a wife has the primary role of a mother (rather than a sex partner).
A pornographic lifestyle & outlook is the opposite of compassion & the development of spiritually strengthening & liberating qualities. 

user111: Technically, watching porn doesn't break the 3rd precept, but it weakens it. In other words, it weakens the merits you gain by keeping to the precept apart from  accumulating bad karma.
