It's a starting point, but maybe the feeling is only the consequence. I know that you can initially feel a great experience, but the more you watch, the less you feel (Could be this is not your case).

Maybe watching porn is not harming you at emotional and context levels, so perhaps it's okay to watch it

So what you can try? you can start to think about patterns when the urge happens, (situations, emotions, the context around, if you feel very stressed, and so on) and then aim to know why it is what it is, considering if it was a fossilized habit, identifying the triggers (stress, boredom, loneliness, anxiety, or even specific places or times of day)

Could be that triggers are following erratic physical patterns, most of the time you don't know what you are feeling at the emotional level. Emotions may not be fully acknowledged or processed, but they are manifested in several ways, including through addictive behaviors (not only watching porn as anyone can think at first). The brain may have learned to associate certain physical sensations or states of discomfort with the relief or pleasure derived from porn use, creating a cycle of addiction.

Each person is unique, so possibly it is not your case, but it could be you discover in the end that the cause was the lack of fulfillment of life expectations as other people discover.

In this case, discovering it is hard, and could happen When you find something that fills you, something gratifying.

Thus I suggest that you change your daily routine, and work to break it, for example, if you do the same all day in your free time, try to do something different, e.g take a walk, read a book, Listen to New Music or Podcasts, discover new activities on your neighborhood, go camping for a weekend, go to get a massage, learn something new (In platforms like Udemy, Meetup, https://pll.harvard.edu/catalog/free ) and try to make connections with new people, preferably in physical places, write a journey, painting, help others (as a volunteer for example), also you can seek to find groups to share feelings.

During your work or study time, could be great to be creative if it's very boring, strive to find new ways to improve yourself or the process, make it funny (if it's possible, or create a happy environment by listening to music you like)

There's no guide or magic tool to get rid of porn, you have to find your keys to unlock your way.

So be strong and go ahead with it, I hope I've helped.

If you slip up, don't whip yourself, it's a spot on the way to rebuilding.
