It's normal. These is no cause for normal. Nor is there any special care.

So you think that there is nothing else to worry about? Is there any special care I should take of the location? What could have caused it?
No, this resolution is pretty impressive. The photos show a cyst of the type commonly found on the penis. The cyst looks irritated, either from masturbation of popping. The white stuff that comes out of cysts looks just like what you're showing. My advice is to leave it alone, forget about it, and shoe whatever's left of it--if anything--to a doctor, next time you go.
Take care.
