NSFW - Idea on what this is?

Hello,

image

I have frequently masturbated most of my adult life. I started noticing this happening over the last few days. This is painless, does not itch, but has me worried. In the past, I have had unprotected sex but I have no signs or issues until now randomly... this has me worried after a few google searches... possible gential warts or herpes. Any help is appreciated.

they look harmless

Could be a little dermatitis, however, it has some characteristics of HSV. It never hurts to get tested, I would just recommend a test to make sure.
