1st Time Trying NoFap Challange. Any Advice?

I came to self realization last night that I need to stop masterbating and looking at pornography. I am hoping that stopping masterbating and watching pornography will make my sex life better with my wife. I have a few questions.

Does using the forum to talk about the difficulties refraining from pornography and masterbation help you become less resistent to break the challange?

Has anyone seen sex get better with their wife after doing the nofap challange?

What are some of the urges and feelings that I am going to feel by doing the challange?

What realistic changes will my body go through over the next few weeks?

Any advice you can offer to coach me would be greatly appreciated.

 

Thanks
