Porn is only "good" for cooming, which is a self-perpetuating degenerate cult. Porn is unnatural: it's needed for masturbation when a coomer's body can't naturally keep up with an addicted coombrain. If you have a "perfectly normal", natural urge to masturbate, why do you need porn? Indeed, people with limited mental capabilities who have never been exposed to porn just grab their privates and go at it, to the dismay of caretakers.

And "celebrate" ejaculation? It's a body function. Why not "celebrate" other body emissions - piss, shit, phlegm? Disgust is natural. Our ancestors put it to good use avoiding disease. Religion may or may not be outdated, but the desire to avoid disease is as relevant as it's ever been. Ignoring this natural urge to chase a high we're not feeling that you arbitrarily insist is moral to feel -- that is absurd, irrational, and cultish.
