Now that I have a foreskin, I dare not let my friends know, for fear that my friends will laugh at me.

It's not like going to the hospital at all ... besides, it's good for your health after the operation, and your friends will be happy for you. As for being afraid of jokes, I believe that even if your friends laugh at you, they are absolutely well-intentioned and don't mean to look down on you.

Don't think too much. After a long time, the influence of surgery on you will fade. When you look back, you will think it's no big deal.

Good luck, hehe
