@amiableFig7651 It may be helpful to explore why do you watch pornography in the first place. You may say '"It is pleasurable", but note, it is actually bothering you.
Pornography is often used as a tool to numb out uncomfortable feelings. It is also used as a substitute for real connection. It is a cheapening of sex. No real intimacy is reached through pornography- it can be a way of avoiding it. There may be other immediate motivations: boredom, lack of a sense of meaning, absence of other coping skills, affective immaturity, loneliness.
You may need professional help. Our brains weren't made for addiction. Addiction is a hijacking of the brain. Psychologists help make the unconscious conscious so that you can figure out your problems and solutions.
A habit needs to be substituted for another habit. If you find what is the problem or the feeling that you may be trying to cope with through porn usage, you can make plans on how you think you could better deal with those feelings and solve those problems. Porn may also give you a feeling of control- until you realize you don't actually have it.
If your trigger is boredom, you may want to make plans on how your are going to have fun. If it's a routine habit, you have to see what else you are going to do in that time in which you watch porn. If feelings are your trigger, you may have to read about managing emotions and how to safely experience those feelings, gradually, until you learn to tolerate them (akin as how we learn to tolerate very spicy food). If places trigger it, you may want to avoid certain places, or, let's say the trigger place is the bathroom, stick to a strict rule of no smartphones in the bathroom, phones and screens off in the bedroom, etc. It will be uncomfortable. But you CAN tolerate it. Then your brain can rewire itself.
Think of all the good things you can achieve through stopping porn usage. You'll have more time and energy for other things, including interactions maybe with real women or real people. You would feel proud of yourself: you have more control of your life, more control over your impulses, you will have proven to yourself that you are free. You could improve in several areas of your life of your choosing.
You would probably need to give up masturbation. Sexual imagery created by your mind isn't much different from the one on your screen. It is okay, good and healthy to give up such behavior. It is hard at first. But resisting it also gives you the opportunity to realize what you were feeling before you wanted to do that, and realizing what you were feeling and why can give you a chance to face and solve the situation. Pornography consumption leads to consumption of ever more explicit, violent pornography, which in some instances leads to the consumption of pornography that contains actual rapes and children: by stopping, you help reduce the future demand for this awful product and help keep men, women and children safe from sexual trafficking and sexual abuse, and save yourself shame and self-disgust. You can also become a light for others to quit.
Thank you for sharing and talking about it. There are online support groups of people giving up pornography. You are not alone. Hugs.
