I am doing well with NNN

It's the 19th November and i'm still winning against my addiction to porn. First I was struggling and also sweating when I was near a girl. I felt like my balls were moving. But I have found a solution. Everytime I have this feeling I start punching my balls with my left hand (the weaker one). Then the feeling disappears. But I don't think this is good for my fertility. Do you have any suggestion on how to make this feeling disappear? I really appreciate your help. I hope I can win No Nut November.
