The UK seems to be very similar to the US in that it is very difficult to find a way of getting completely naked in a medical examination. Any tips on how to increase the odds? Thoughts i had were to go to a country in Europe where nudity was more the norm, also a skin exam looks like the best route to take.
Don't want to disappoint you, but getting a nude exam is hardly the norm in Europe either. Doctors don't have the time to wait for a patient to get undressed and dressed again, nor, I suspect, do they wish to become suspect for conducting exams in this manner. A little bit of gossip can go a long way and this kind of reputation (getting patients out of their clothes for any which reason) can give a doctor a bad reputation.
You'd perhaps think that a dermatologist would conduct nude examinations, but in this regards too I've had experiences together with my wife and it seems that they too do not require nudity to conduct their preliminary appraisals of a patient. Care is taken to preserve the patient's modesty.
If you really want to experience a nude examination, your best bet is to look for either an amateur or better yet, a professional play doctor. The professionals will be pricey no doubt, but you will at least get what you are looking for. No frustrating hints that are ignored, no talking at cross purposes, no uncomfortable explaining to do when the doc feels there is something odd about your complaints.
The best places for medfet experiences should still be in Germany. Some of the photos of their setups look like the real thing with every conceivable instrument available for use you can think of. The 'doctors' and 'nurses' are however usually a bit more skimpily clad than a real professional though ...
Here, for instance is a link to more links in Germany. All commericial though, just so you know:
