We complain a lot about why men in this era lack masculinity and are not fulfill the traditional role they used too. And a lot of that is because porn has became so widespread. what give a man masculinity biologically is testosterone, and testosterone is mainly produced by the testicles and contained into the semen. Every time a man jerks off he looses it and his body needs time to produce it again.

Some people complain that there are no studies about it, and is true..but this is also due to the hardness of trying to conduct such studies and interest in them. But there are a lot of positive stories.

here is why a lot of guys on /r/nofap or /r/semenretention, report how they changed seeing the other sex, and improved their confidence over all.

Also i'm not saying this wil make men change and become instantly the best version of themselves but is a requirement and a step among others
