Hey everyone! Hope you're all having a great day/night. So, I'm sure you've all probably read something similar to this 1,000,000 million times over, so I'll try to be brief. I received unprotected oral sex from another male approximately 1-2 weeks ago. I ejaculated into his mouth, and he swallowed (not be too descriptive, but I want to ensure I cover everything in case it's relevant).
Fast forward to today, a few hours ago while in the shower, I noticed a small, white pimple-looking spot under the head of my penis. There was small amounts of pain present (mainly if I pressed really hard on it, but it didn't just "naturally" hurt). There is only one of these, and I currently have no other symptoms.
I'm just curious as to whether or not it's something to be concerned about. For detail sake, I will state that I do masturbate several times a day, usually without any type of lubrication, and it can take me quite awhile to ejaculate (so there's a lot of friction for a good amount of time, is the ultimate point).
Anyway, any and all help/advice/etc. is appreciated.
Thanks!
