People who think that fapping makes you go blind are not very smart. The whole idea that fapping makes you blind is an old saying people use to use to scare people away from masturbating, and it has no real meaning. This is not to say that fapping is not without negatives, just that it is not going to ever make you blind. If you watch the second Friday movie you can see how this joke is used. Please don't believe all these people who think that semen retention is going to make you a super hero either, and that busting a nut makes you unhealthy. They say that some ancient Chinese medicine proves that this is true, which is utter bullshit. If you want to embrace all this ancient Chinese medicine stuff, next time you go to the dentist to get a cavity removed, just ask the dentist to not use anesthesia. Then you will see how all your Chinese medicine is going to help you there.
