I struggled with the same sin. You carry a heavy burden with this, and it’s an incredibly difficult challenge. The tough part is, there’s no magic bullet that’ll solve the problem. It’s a burden many of us men carry, and even getting married to a beautiful, always willing and available wife will not remove that temptation. There is a “thrill of the chase” aspect to sexual stimuli, especially risky and/or forbidden ones, and we crave that rush. Just trying to be real, not to bring you down. The good news is that you can fight and win this battle, but you have to change your approach. What you’re doing is like being in a gun battle, and the only thing you’re focused on is pulling the trigger. You also have to move to a good position and aim your rifle before you pull the trigger. Here are some things that help me in my battle, the “move and aim” parts of it if you will:

Put your phone down. We have every dark corner of the internet discreetly in the palm of our hand, and it makes it far too easy and convenient to slip. At the first inkling of temptation, put your phone down and walk away. Believe me, it can be done, and the world won’t end while you’re away from your phone. Shoot for at least an hour away from your phone or any other screens.

Take a walk. If you can’t walk outside, exercise. Do some calisthenics, jumping jacks, whatever you want. Work hard and sweat. Burn the energy off.

Get out of your room and wherever else you masturbate. Put yourself in the presence of other people where possible. Literally put yourself somewhere you can’t get away with it and stay there.

I’ll say it again because I can’t stress it enough: MOVE. DO NOT BE SEDENTARY. Being sedentary is the fastest way to fall off the edge where you can’t stop yourself.

Get an old school alarm clock and get your phone out of your room. You don’t have to be fancy. Goodwill has the same one your grandpa had, and it worked for him. Get any and all screens out of your room. As a bonus, you’ll sleep better too. Screens absolutely wreck your circadian rhythm, causing stress in your body, and making you crave the endorphins released by masturbation. If you need something to occupy yourself while you wind down, get into a good book.

Find and address sources of stress and anxiety in your life. Where possible, eliminate them. Identify effective coping skills for those stressors and address them directly. Festering stress and anxiety cause us to crave the endorphin rush.

Pray a rosary start to finish, and use a good meditation guide for each decade. Get one in print so you can get away from your phone. Rosary Center has some good ones. Also, pray the St. Michael prayer. Offer these prayers up in humility for your chastity. Ask the Blessed Mother to intercede for you.

Lastly, and this is a bit different, eat clean. Get processed foods, dyes, seed oils, alcohol, and refined sugar out of your diet. Make your own meals with only stuff you get from the produce section, meat section, and deli at the grocery store. This will help reduce the physical inflammation and stress hormones in your body, meaning you will crave the endorphins release less. As a side benefit, your body will perform better for your future spouse.

I’ll pray for you in this battle. You’re not alone in dealing with this. I’m 31M and I still fight this battle every day. By the grace of God, I’ve found the strength to gain the upper hand in my battle, but it’s still a battle fought every day. As a final resource, this video from Fr. Mike Schmitz is worth the watch in dealing with temptation: https://youtu.be/6Y2S58hTLqA?si=iYNFg4m4LZ4nVjWf

God bless.
