Most men have the phenomenon of having a longer foreskin to some extent. In more severe cases, it might be phimosis. Of course, phimosis needs to be resolved through surgery. However, if the overlong foreskin is not serious, one can make an effort to expose the glans regularly.
How to do it yourself? That is by frequently retracting the foreskin. Normally, during the first attempt, you should gently try to retract it. If the foreskin easily retracts and exposes the glans without any obvious discomfort, then this kind of foreskin doesn't require much effort. As the penis develops, the foreskin will gradually retract on its own, and even without retraction, phimosis won't occur.
Some people may have more severe conditions. For those who, when retracting the foreskin, find that due to the small opening of the foreskin, it cannot be retracted to expose the glans, and experience noticeable discomfort or even pain, they shouldn’t force it. Instead, they should progressively expand the foreskin bit by bit. Through multiple manual expansions, the opening of the foreskin will gradually widen, the foreskin will slowly shorten, and ultimately, the hidden glans will "emerge."
It's worth noting that for some cases of overlong foreskin, one mustn't rush. This isn't something that happens overnight; it may require long-term continuous efforts to make the foreskin adaptable to retraction, finally achieving the goal of loosening.
Therefore, when retracting the foreskin, one must be careful. Manual retraction of the foreskin cannot rely on one or a few attempts to achieve the goal. It's essential not to rush, as doing so could lead to counterproductive results, such as tearing and infection of the foreskin, which could worsen the condition of the foreskin.
