Does this look like chancre/blister?

[nonc]

Hello all,

It’s been only recent that i am becoming more concerned about my body. As a result, there are unfamiliar aspects of my penis that i’ve no idea what they are.

I’ve never had unprotected sex before.

Why does my penile head look so wrinkly??

Does number 3 look like a chancre or a blister?

I would appreciate any help or advise what are the circles parts of the penis?

Thank yoy very much
