I stated NoFap because porn was really fucking up my mind, for some reason you start in regular porn than you go to some fucked up shit. It's been 30 days sice I started NoFap, and I feel like an animal, I want to fuck Evey single time, i'm getting a boner just by seeing girls in thing clothes, and this make me feel a bit scared because I have a girlfriend and don't want to cheat on her is this normal??
I'm not at 30 yet but I have some similarity. Before starting I hardly got thinking about sex when seeing lightly clothed women (I'm happily in a relationship for soon 3 years). Now I more easily get aroused seeing some skin (or at least I imagine it is because of Nofap) and also got worried that I don't love my partner, but hell no - we got something better than a nobody that gave some eye contact. I think its normal going through this.
Just hang in there until you flatline. Soon your private parts will become basically unresponsive. Then after that you will lift out of it and have a much healthier sex life.
