You can indeed pull off a submissive male doctor! So I'll have to strongly disagree with JimmyJohnson that she must secretly want to submit. I'd go with the power dynamic she wants the first time and suggest reversing the dominant one next time if she's happy with her first session.
For her:
- must act extremely comfortable about every procedure
- she can then be a very no bullshit patient with no need to beat about the bush
- example: she strips her bottoms off, lays back in the chair/table, and unceremoniously swings each leg out into the syrups, and scoots down without you asking her
- annoyed she says "Hurry up. I have places to go."
- you drop the speculum and need to go get a clean one
you:
- very uncomfortable and nervous
- new doctor? Just a nurse filling in? She owns your clinic?
- due to your nerves you stammer while explaining what you want to do
- you: "Um, I, ah--- I need to. you know.... check those parts."
- her: "Do you actually work here? Get the speculum. Vulva, not "those parts"" (she check her phone, bored and annoyed)
She may the patient but you are following her commands. You might always check a patient's vulva as part of your routine but this time you do it because she tells you to, wishing she had chosen a competent doctor.
