Pearly Papules and "thick" Corona

So i noticed Papules last week, informed me online but meanwhile i noticed (maybe i am too detailed) that the corona "continues" with a white color and is thicker than the rest skin. I do not know if it's an inflammation or something but i think that the Corona should stop where the red skin and papules stop. I want to know what's wrong till i can visit a local doctor. I was in a school trip so i couldn't easily go to one I'm 17 years old, so I'm in puberty. The Papules are normal, my dad recently told me he had them too. But the Corona form makes me worrying.

I think this is just the way the head of your penis has developed so far. You are right to suggest that the corona would generally be quite clearly defined, but at this point in time your’s is not.
As you say yourself, “you are in puberty” and what can happen is that your penis can quite easily continue to develop until you are in your mid-20’s - so there is a great deal of scope that by the end of your natural development the ‘landscape’ or natural architecture of you penis could look quite different to what it is anyway.
If you put it in basic terms, it is very unlikely that you have a physical condition that is causing this, and I think if you saw any medical professional they will simply say ‘there is nothing to worry about’ and that this is ‘simply a normal variation’ ,

That’s really great to know. Thanks a lot. I’m going to check it sooner though, even if i don’t have to stress about it (even my father doesn’t think it is important xD)
But well.. there times where i have to check things to be sure. And to be real, a veery long time passed since a doctor seen me naked so yeah. On such age i have to know what’s developing. Oh and yeah the Papules are genetically. My father had them too lol

Okay, thanks for the update - good luck …
