Masturbation is a form of sodomy. which is to say that it is a practice done by sodomites
Remember what Onan did. He spilled his seed on the ground, which was detestable in God's eye. Yes Onan didn't rub his junk with his hand, but he still masturbated with a woman's vagina. So it is still the same thing.
Even if you don't believe the bible, porn is more addicting that heroin and has many adverse effects on the brain including but not limited to:
-proclivity to keep watching more and more degenerate things
-get a bad impression on what sex is and how to treat women
-get an overall obsession that will torment you if you try to quit.

There is a reason why God wants sex to be only for procreation not recreation. Aside from the aweful things it does to your brain, it also adversely affects society. Because once a society sees sex as recreation it is only a matter of time until baby murder becomes a viable option to continue the cummies and destroy the family unit. kinda like what happened in Sodom, hence why fapping is a form of sodomy
I used to be a degenerate like you, OP. No matter how many times I tried to quit on my own, my urges would torment me until I found release. Than I started to pray the rosary. Ever since I started praying the rosary daily, I never had urges to fap or even had nocternal emissions. /ourLady/'s rosary cured me of that sin and others.
Pray the rosary, OP , if you want to be free from the shackles that bind you. Pray the rosary if you want to know God's love. Pray the rosary if you want to see the change you have always wanted to be.
