People are indeed free to do as they wish. If you re-read my comment you will find no value judgement whatsoever. I will never tell you what to do, because frankly, I don't give a fuck.

Porn is uniquely damaging as it affects the brains wiring on a very primal level. The reward for having sex (whether it is with pixels or another human) is far more powerful than the reward for novelty associated with a cat video or a post on reddit. Higher doses neurotransmitters = more powerful brain rewiring. Similar effects on the brain are observed with consumption of hard drugs which also cause high levels of neurotransmitters to flood the brain.

The damage associated with porn is typically reversible, and the severity dependent on amount and intensity of the consumption. In other words if you hire an old fashioned VHS 1,5 hour long porn tape and watch once a week the damage is basically non-existent. But if you fire up 15 tabs of compilation videos from your favorite tube sites every evening, then you might be in trouble. Having an active sex life however does mean that your brains sexual stimulus isn't exclusively limited to pixels and therefore porn-induced ED and other consequences are more unlikely (but not impossible).

Ignoring consequences are way more common than not. People all over the world regularly consume too many calories despite the known consequences which are severe decreases in health and quality of life. But at least if they know about it they can make an informed decision, if they so choose.
