Help! updated

I had dental work today and they were pulling pretty rough on my mouth, I’m pretty sure they got it a couple of times. Later on I gave my bf head. He’s only been with one other person before we were together. He swears it’s not an STD but I worry about everything 🙄 we’ve been together for 8 months and this isn’t the first time Ive done it and theres nothing off about his willy, looks perfectly fine. So I’m thinking if it was one it would’ve already showed up.. my mom says its probably from the dentist.

Update: here is my lip from the morning after
