I developed a red bump on my penile shaft after intercourse. Could this be herpes?

Hello doctor,

I am 26 years old. I woke up a few days ago with a red bump on my shaft. I recently had protected sex with a new person, which is why I am worrying. There is no white head or hair. It looks deep, but I am not sure if that is the regular depth for a blister or pimple. I put some pressure on the bump, and a little bit of pus came out, and the bump now looks skin-colored. After a few days of making sure it is always clean, the bump is very small, almost non-existent. However, the skin is shiny and looks like a blister. It was not itchy and never burst open. Nor does it hurt unless I put pressure on it. However, if I stretched my penis, I could feel the discomfort. My symptoms are non itchy, the pain only with pressure, no clear fluid, ulceration, tingling, or constant pain. My temperature went up to 98.7. No aches or unwell feeling. I am trying to determine whether this is just a pimple or it could be herpes?

Thank you doctor,

Here are more pictures. If not herpes, please let me know what you may think it is.
