ok well this is a tricky question. Clearly, the Catholic priests think it is wrong and a mortal sin because of the LUST that is involved in watching porn. When you say "is it wrong?", do you mean in a spiritual sense or a popular-culture sense??? Because in our modern-day culture, it is totally acceptable and viewed as something "normal". But in a Spiritual sense, think of it this way: if it is not something that God would be proud of you doing, do you think it is right? Now im not condemning anyone for watching porn because I have done it before. But all you need to do is to listen to your heart and soul and there you will find the answer.
I hope I have helped you some.
God Bless you
p.s. I know you will do what you think is the RIGHT thing to do
