12 years old, don't worry, even if you have surgery now, you don't have to do it. What's your situation now? Try to turn it over yourself and see if you can. If you can, you will be fine. Don't turn hard if you can't open it. Wait two years and see what it looks like. Because you are now in the development stage, the penis begins to develop rapidly, and some will open automatically with the development of the penis. Some really can't be turned over. Even if it can't be opened, it is better to have surgery after 18 years old. At that time, penis development was over. Surgery is better.
