Is nofap going to work for me?

I am 19 y/o
I watch porn on daily basis
one day i was making out with my girlfriend but couldn't feel anything down their but when i started thinking of it to get hard it started getting hard
Then suddenly one day i couldn't get hard to porn i was totally fucked up like why is this happening so i thought of not watching porn for few days. The next day i had my morning wood and got erect not that hard so i thought of trying porn again but couldn't get hard
so i will like to ask will nofap will help me to overcome this problem as i have just started it for like 2 days, I get random hard on but not that firm.

How NoFap works to the body?
Will NoFap work for me?
