NoFap has a lot of benefits, but it doesn't fix the beta mentality.
On a different subreddit, a NoFapper who picks up the hottest chick at a bar shares his story. He has an amazing time with her and the sexual tension escalates. Two hours in, the chick wants this guy's dick, so he asks her to go to his place for a drink.
Once at his place, it's gets pretty heated. The girl is on top of him, kissing him and acting like a complete slut. However, the NoFapper notices that she began to slow down so he asked her if something is bothering her.
She told me she'd been on the bad side of hook ups recently and only wanted to go further if this was going to be the real deal. Right then and there, It would have been so easy for me to lie, say I wanted the real thing too, and proceed to get her naked.
Here, his 'White Knight' beta mentality kicks in.
But because of NoFap I saw her in a new light. She wasn't just an object to be lusted over. She was a real girl who had experienced real pain. She was trusting me to make a decision and I could not let myself hurt her. So I told her the truth. I told her I just got out of a 6 year relationship a few months ago and was not ready for anything but a hook up. I told her I could have manipulated her to get in her pants but she, being an amazing girl, deserved better. And I told her she should go home before I hurt her more.
This NoFapper had a hot chick ready to fuck him, but decided to be the 'good guy' because he 'felt bad' for her. He later on goes on and says:
I could not be prouder of myself. I'm a new man. A rare breed.
A new man? Sure. Maybe you got rid of your degenerate porn addiction, but you're still a beta cuck. She was at the bar because she specifically wanted to fuck. She will be riding Chad's dick the next night and have no memory of you.
Tl;dr: NoFapper has a chance to fuck a hot babe but his beta white-knight mentality kicks in and he cock blocks himself. He later on justifies that what he did makes him a better man.
