Is this herpes? Doesn’t itch or burn but I can tell it’s def irritated

around the end of july I received oral sex from someone, however they did nick the tip of my penis with their teeth which I initially thought caused the irritation but it’s been a couple months now. HIV/Std tests came back negative but idk if to get tested for herpes cause I’ve read about false positives… it also doesn’t itch burn or have any pain at all

not herpes

That doesnt look like herpes
