I can't believe that anyone would seriously ask this question! Anyone who doesn't consider watching pornography to be a mortal sin has a seriously defective conscience.
If the OP doesn't want to think it is a mortal sin, he needs to stop fooling himself.
The OP asked a fair question, no need to get judgmental on him. He didn't give his opinion nor say that he has ever viewed it. And yes it is believable that some people can be confused about porn. For example there are protestant "mega churches" out there and some doctors that recommend porn tapes as marital aids or all things.
Porn absolutely can be a mortal sin as can using ABC, missing mass on purpose (sunday or holy day), murder, refusing the marriage debt, getting drunk on purpose and a number of other things.
If you can't believe anybody would ask this question, here is a rather common example - a young man who was first exposed to porn at say age 10-12 by an older brother,"friend" or even a father, becomes addicted very easily as he goes thru puberty. He grows up ashamed of himself and with extremely low self-esteem. He then at some point has the courage to ask for help on a religious website....
