If in your daily life, you have impulses to masturbate, and you have difficulties not obeying them, and it consumes a lot of your time and energy, then you're addicted.
But it's not some sort of inescapable bond.
It's just that your daily life makes you frustrated and miserable and so you fill the hole in your feelings with orgasms.
Change your life and the addiction disappears.
It's like these experiments with rats and heroin. Put a rat in a cage with only a pleasure button, it will keep pushing it.
But if you give it space to live, stuff to interact with and other rats to do rat things with, it will ignore the button.
