Patient's question:
At what age does a boy's penis become erect?Doctor's answer:
It varies from person to person, as everyone's physical condition is different, and development differs as well. Moreover, a significant portion of people have an overly long foreskin, making it impossible to expose the glans without surgery or manually retracting it. However, under normal circumstances, boys generally cannot retract their foreskin until they are around 13 or 14 years old. Of course, there are also some boys who cannot expose their glans even after retracting their foreskin, in which case a minor surgery would be necessary.
