It is just a papule. Not serious.
Observe for some time, if there are any changes, go see a doctor.
If anyone else could please help, my anxiety has left me shaken to the core over this and I won't be able to see a doctor until Wednesday due to the New Year. Thank you
PPPs don't typically appear on the shaft. https://emedicine.medscape.com/article/1058826-overview
Obviously, only a doctor will be able to tell you what this is.
Let's go "worst case scenario", and say it's a wart from HPV - then what? Lots of doctors in the field feel like HPV is an inevitability for sexually active people with more than 1 partner - something like 90% will have it in their lifetimes. Yes, it can lead to some problems, but for the VAST majority, it clears from the body within a couple of years, and causes no problems.
If it is HPV, and I am not a doctor and can't tell you that it is, and I didn't look at your pics, either, then it's not from your most recent encounter. The incubation period for HPV is 2 weeks to 8 months, with the majority appearing 2-3 months after infection. I don't know how active you are with how many partners, but many people never know who they get it from.
Again - I'm not diagnosing you. I'm on a work computer so don't look at penis pics. I also can't diagnose, so I don't look at pics. I just want to help you not be "shaken to the core". Whatever it is, you'll be just fine. :)
