Was never asked as a child n teen. It was simply inserted and it registered. Now, my boyfriend does twirl, twist n reinsert, moving it in and out during play.
When I get my coffee enemas, my rectal temperature is taken first with the older glass mercury thermometer . If my caregiver were to turn it I would be fine with that. Given the nozzle she’d be inserting up my behind; after taking my temperature ; no the turning of the thermometer would be no where near as intense as that inflated nozzle up my rectum…and it wouldn’t need any turning!
