A couple concerns with my penis

Hey everyone, the tip of my penis opening is more red than usual on the left side. I noticed after masturbating, is this something i should be concerned about? Also, while I am not fully hard, the way my skin clumps together kinda concerns me. I'm talking about the area right above the mole in the second picture. Is this something to worry about or am i just imaging things? Thanks in advance.

What is your sexual exposure?

Had protected sex about 3 months ago.
