When you learn how to handle urges correctly by feeling your way through them, your overall desire for porn reduces significantly.
Why?
Because you know how to handle an urge and it becomes no big deal.
After the first time, you get better, and you get more comfortable with it.
Once you do it enough times, you don’t think about it as much and then you’ll notice the desire for porn starts to go away.
You might have a thought followed by a brief urge before your brain kicks in and says, ‘I know what to do here, this is nothing.’
