excessive porn and masturbation..

I am male 22. Was masturbating to porn since 10 years. Sunce 3 weeks I have gone with out pmo. I did not notice when did my morning wood start vaniahing away. From last few week I had no sexual urge. I am a virgin and have not I dulged in the intercourse. While masturbating I had realized that I was being excessive.
After 3 weeks I have notived gradually my morning wood returning though dey r just 20 percent hard. Had some random erection in college too. But im not sure about my hatdness. Hope im able to get it back.
I guess im already in flatline too. Yeah..mood isnt the same as ovbious. One seems to be curious anxious and depreases. But one has to fight and stay normal.
How old r u?
