What is this

I’m going to the doctors later on this week but it hurts and I don’t wanna go to the ER but when I pee and pee gets on it , it burns bad asf on that sore or whatever it is...it wasn’t there til few days ago the underwear I had on were a little fitted and the line of the underwear was squeezing against the inside of my cheek..so I’m hoping this is why that’s there....idk but glow and google has me thinking its herpes which I doubt but omg 😑😑 sorry the TMI, and it’s not from shaving because I use NAIR now. I know the day I wore the underwear my boyfriend and I also had super rough sex so idk if it’s just a tear or what idk guys
