Excuses to stay exposed longer (and quasi-introduction)

Hey guys!

I'm brand new to this site, but I have a huge medical kink. For me, the kink comes from being exposed/embarrassed in front of the doctor (or the nurse!). Unfortunately, it seems more and more doctors are making it the whole experience less embarassing and have the patients exposed less and less. For example, my new doctor has me put on a gown (or gives it to me assuming I'll be more comfortable), and I rarely am exposed to him or the nurse at all. I have a physical coming up soon, and I'm wondering if you guys have any little tips for subtle excuses I can give to be exposed longer. Goals include:

Getting undressed just to my undies and not having to wear a gown.

Being undressed in front of the nurse.

Prolonged time in my underwear.

Exposing my bare behind.

Any tips would be welcome. Thanks!

P.S.: I also have a huge sleeping gas/sedative, and hypnosis kink (though there's probably no way to incorporate that into a physical 😜)
