Like when the doctor is doing an inspection or examination of your parts, and then they talk about your parts to either you, or to an assistant. Or “I’m going to look at your _____ now.”
Do some of you get sexually aroused or horny when the doctor or nurse verbally says things like “your vagina/penis,” “your anus/butthole,” ”your breasts,” etc.? Or even more specific parts like your urethra, clitoris, labia, testicles, nipple, bellybutton, etc.? These are things people do not normally talk to you about, let alone point out. To add on, how do you feel when the doctor is doing the visual inspection on you? What are you thinking about?
For me, I think it just goes back to the fact that they are seeing parts of you most other people never get to see. And now they are talking about these parts, as if they are letting you know that they do, in fact, get to see it.
