This was to my last question

Can ear noes and throat question. I wanna stay anonymous. But it I'm still a virgin and I only did oral for like 15 min nothing went inside my mouth. Do the orthodontics can tell then if I had an std or I would have to go to an obgyn. I'm really paranoid. This event I had happen in November with me an my boyfriend. And I have been to them and they said I'm find but just to make sure can they tell.
