Umm....maybe? I'm not sure...but what I am sure of is that doctors know it's a normal thing for teens to do, so they probably wouldn't be surprised. I do suggest not bringing it up in conversation, though. Only if they ask you; be honest....but if they don't, I think you shouldn't mention it. Good luck!
Well, I dont know how can I say but if you just do that locally no problem. But if you go to "inner places" than he/she can maybe tell when he/she is examining that location. (I know a doctor, I asked this question to her after I saw your question)
Yes. Doctor- "Let me check your pulse" "Ok heart beat now breath" ........"Do you do you o my gosh" ...... He will then stand there and confront you O_O Jk . I highly doubt he could tell just by doing a regular check up unless you are getting a "lady" check up.
What the hell?... Uhm you shouldn't even be doing that you're only 13 years old and if really doing that then I'd have to guess you're sexually active. And I don't think the doctor could actually notice that you do that unless she/he were to do a grown woman check-up on you and I would prefer it to be a woman instead of a man. But that's your choice when getting checked out I would instead want a woman doctor I really don't trust men doctors. OH GAWD WHAT A QUESTION FOR A YOUNG CHILD! O.o
