TF is this? Red bump?

It's happened once before but it went away. Now it looks a ton worse and I'm scared. My boyfriend said he's clean but you can only trust someone so much and I'm scared it's herpes. We use condoms but they arent 100% for protection against STDs. I'm gonna run to a doctor ASAP to get it checked out but I thought I would see if anyone has seen anything like it on themselves or others. Maybe something to ease my mind idk.
