There have been moments where it's just been obvious that I was relaxed and not uptight about being undressed or nude in front of the doctor or nurse, and this has been commented on. I've usually told them that I model for artists and art classes, or might mention that I'm a nudist. Sometimes it's been relevant to the exam, like when I was seeing my dermatologist for some superficial skin cancer tumors. She was asking questions about being in the sun, how much exposure I get, and so on. So, I did tell her that I'm often nude outside in warm weather, and do nudist activities. This wasn't alluding to any Medfet interest, though. I wouldn't do that with that particular doctor. She's very professional and matter of fact in her conduct, and I respect that.
It also depends on the doctor, or setting. There are some medical professionals whom I've been more comfortable with than others. The conversation may range into personal things such as my interests. I've subtly mentioned interests which could lead someone familiar with Medfet to catch on. This is more likely to happen with someone who I won't be seeing on a regular basis for future care or treatment. But, there are some, probably most, who I wouldn't do anything of that sort with, it just doesn't feel right.
After I had surgery, a few months ago, there was a med student from my surgery team who came to see me in my room. She wanted to ask me some questions, I think to get a better idea about how I may have come to need this surgery. So, we had a conversation about my lifestyle, interests, background, etc. She remarked on my casual attitude about much of the medical procedures and practices which make others nervous. I did say that I find much of this to be probably more interesting than many people. She laughed and said that was unusual in her experience. I think she was curious to know more, and maybe I would have let on more if we'd talked again, but she hasn't been a part of any of my follow-up visits.
