Bettering my life

I'm pretty young, not going to say how young but I can buy alcohol in my county so I'm not a child.

I find myself needing more extreme porn each time I go to porn sites, and one fetish i randomly came across an accident disgusts me. so much so that I have thought out ending a relationship in hopes this fetish will go away. when I'm not horny and think about it, I almost instantly get horny but get stopped by disgust and worry. its affecting my life in bed as I take a long time to reach climax and she feels bad because she thinks she doing a bad job, which she is not it's just I need porn to get me to the climax.

that's why I want to start nofap. I also read about loads of other benefits that come along with it so hopefully, i will stick at it, keeping updates on how it is going should also motivate me to keep going.
