I got this friend of me, i can't get him to participate in nofap. What to do ?

So here is the story, my friend from the group in university, he faps and loves it, and is addicted, and i try to convince him that this has no positive effects on him and it's stupid, but he is so damn stubborn and he rationalizes everything i say and defends PMOing like it's the purpose of his life (it's not really, but he surely does it)

So he suffers from these negative effects, and doesnt even see them, and he is constantly feeling lonely, has no GF, constantly worried about approaching girls, very shy, never social, can't hold a conversation, wears glasses and looks nerdy, has acne on his face, speaks quietly, has poor pronunciation, (i can't understand what he says many times), his posture and body are manly, but he is kinda not the one that a girl would like to talk to. Sometimes he is very perverted and horny, and looks at some girls when they pass him by, but not the eye contact thing, you know, he looks at the things that arouse his sexuality, he doesn't realize he is addicted, and has no courage to start talking to girls, sometimes is very anxious and paranoid about what girls would think about him, and very precautious not to make himself embarrassed infront of a girl with something that he says, for example if he says something to a girl, or to another guy and a girl is close to him and hears what he says, then he is like : What if this girl thinks of me that i am a pervert, a nasty guy, a traitor, and bunch of other things like this. He is always concerned about his looks, appearance.

He often asks me does he look manly, does he look fat, is his shirt looking crumpled or creased, and many other questions that irritate me when i hear them, i am always saying to him to chill, and to not care so much, but he just cant do it. Very concerned.

So when he says something about fapping, i try to tell him that i don't endorse this, and i dont do it, and i don't like it, but he replies with some defensive thing like : It's normal for a man to do this, and then i say i don't agree, and he says every guy does it, and is convinced that it's normal. This has happened few times so far, and last time i told him that its a self abuse, and he said it's not a self abuse, and its good, and i told him no, i dont think so, and then he asked why, i said because you lose your semen/seminal fluid, and he said, yeah but it restores after half an hour, and i said yeah, but it has impact on other things, and he said you can fap 10 times a day and it will still restore and nothing bad with that, and then i stopped talking about this, since i saw that he can't be convinced of what i am telling him, and he is very stubborn, also, i am not pretty good in having argument with other people, i usually don't win, although i know i am right, and i can't convince so much, unless i could turn the sharp edge and talk to him in the face about how he has ruined himself, but i didn't do it, since he is my friend, and i don't want to use this approach. So please, help me, what to do, and how to make him realize that he wrecks himself with this ???

EDIT: I FORGOT TO MENTION, HE IS VERY DESPERATE TO GET A GIRLFRIEND, AND CONSTANTLY WONDERS WHY GIRLS IGNORE HIM, and he doesn nothing about it, since he is scared of his concerns and worries ... AND HE CONSTANTLY COMPLAINS ON ME FOR THESE PROBLEMS ...

 

both... And by the way, this thought you shared, is very insightful, thank you for it.
