Issue in the ‘intimate’ MALE area (didn’t want to use crude language in title)

Patient: (slightly intimate question but too shy to ask doctor in real life) Why is the end of my penis still attached to the skin by some connection on the back of the tip? This makes it impossible to pull over the head, and as I understand and see through videos, this is meant to ‘break’ loose at some point?

Symptoms: No symptoms, just I imagine it would make some intimate activities much harder and significantly more painful
