This is of course purely an imagined preference since I doubt there is any way to ever realize it. But anyway, I´d love to be brought to an old medical office, equipped with furniture, instruments and accoutrements from the past, let´s say a doctor´s office as it might have been set up in the 1910´s or 1920´s, something very antiquated in any case, replete with shiny white tiles on the walls and lots of metal and glass cabinets and trolleys and exam table. And if possible in an old house from the same period, with floral wallpaper, wood wainscoting, the smell of soap in the hallways or medical disinfectant and things like that.
And then the imagined medical scenario would be to be brought in for a sexual development exam, to possibly pretend there is some kind of arrested genital development or interesting genital abnormality to be carefully and fully checked out, measured, probed and manipulated, all the while being observed by whomever accompanied me to the exam in the first place, preferably an aunt or friend of the family, not by parents.
Another scenario type might be something in the order of being caught masturbating and having a big fuss made about the naughty activity, with ensuing genital and sexual examinations and questioning done in an exhaustive, disapproving and embarrassing manner, without any regard for privacy. After all, in a 1920´s setting, masturbation would hardly be considered a normal activity and that could give scope for all manner of questioning, measuring examining as well as intimate lecturing by doctor and accompanying person, possibly followed by a special course of treatments to help alleviate whatever the perceived or inconsequential imagined problem was. The whole scenario being mainly an excuse to be subjected to exhaustive and embarrassing sexual supervision.
