You release stress.
If you masturbate to porn though its a completely different thing, you pretty much sits there thinking "what the **** did I just did?"
I tend to be more aggressive and sleepy after coming.
Why is this on a teen forum?
You must masturbated to release energy you can build up energy by masturbating and not masterbating. BUT this energy can go sour and if you don't release it. It can make you restless and cause insomnia. That why it good too let it out.
It's temporary. Depression have everything to do with you reacting a moment in your past that you are bringing into the present. Masturbation will just increase those good hormones but it aint going to erase that subconscious issue.
As a result, a couple of hours later, you're depressed again. Hints, it doesn't cure depression.
