You sound like a young chap.
Here's my advice.. not originally mine though. It is from the one who designed and called all things into existence.
Porn is way more addictive than is admitted. Its consequences are way more far reaching than most hard drugs.
Porn goes hand in hand (no pun intended) with masturbation i.e detached sex.
By detached i mean sex with a non existent imaginary fantasy. Sex with that which is not.
I will give you one physical consequence which i hope will make you reconsider your habit.
Erectile dysfunction. A hot blooded seventeen year old using porn can be crippled by this.
How?
It all happens in the brain. I'll share a video to a ted talk so you can get the details from a scientist.
You are not ready to hear the spiritual consequences.
Watch this video fist.
