Look, porn affects people virtually the same, regardless if Christian, Muslim, Hindu, etc. Porn creates a false illusion of what sex is supposed to be, then porn users become disappointed in real sex, preferring the artificial sex they get from porn.
I'm not judging anyone who enjoys porn, watch all you want. But consider this, I appreciate a nice cold beer, so much so that I could drink beer all day. That is my prerogative, there is no wrong in it; regardless, I will still have the effects of daily beer consumption, perhaps even liver damage.
Likewise with porn, sure it's nice to see a beautiful person crying out for all the sex available, but that is just acting. The side effects to porn are negative and include not being able to perform without porn stimulation.
If you lock a man and a woman in a bedroom over night, and they are unable to participate in sex, without any outside stimulation. Something is fundamentally wrong.
Sex is not the answer to life; sex is a break from seeking the answers to life.
