I worried about this too ... but decided what the hell. I'm SURE the nurse and Dr. thought to themselves, "oh look, she shaves/waxes." If I saw a woman at the gym with a smooth pussy, I'd think the same thing
My mom was an ob/gyn nurse for years. Trust me. NOTHING shocks these people (well, maybe Mrs. D's Dr. was shocked). She saw it all. If she felt like she knew the patient well enough, she'd ask questions about their piercings. She said they were more than happy to talk to her about it.
