Celibacy is not having sex. Porn is not sex. That's the problem.
Install a parental blocker and go cold turkey. Good luck.
“Take the example of a poisoned arrow that makes a tiny surface wound. Before long, the poison from this wound will spread throughout the entire body. You must operate on the wound and remove the poison. Similarly, even when wrong behavior does not make anything more than a small wound in the mind, if you ignore it, it will quickly pervade your mind so that it becomes large. Therefore, from the start you must prevent wrongdoing before it takes place and, if it does happen, you must discontinue it immediately.”
- Lam Rim Chen Mo eng v02 pg. 204 tib pg. 444
"All memories and thoughts are the union of emptiness and knowing, the Mind.
Without attachment, self-liberating, like a snake in a knot.
Through the qualities of meditating in that way,
Mental obscurations are purified and the dharmakaya is attained."
-Ra Lotsawa, All-pervading Melodious Drumbeats
"You must experience that the various thoughts, in whatever form they arise, are an empty appearance and not a definable entity."
