“Can you take off your clothes except for your underwear”
“This might be a little cold whilst I listen to you”
“Can you take a deep breath in and out for me. In and out”
“Can you say 99 every time you feel the stethoscope on your back”
“I'm just going to have a listen to your tummy”
“Can I ask you to take off your boxers for me”
“Please turn left and cough for me. And now right. Ok I'm just going to check the boys out now”
Basically I like the same sort of stuff Scotty does - as this thread crosses over between medical fetish and age-play in the tags, as someone who likes to combine the former with being a middle/teen these are the sorts of phrases that do it for me. The one thing I dread in real life (although perhaps would also quite enjoy) is the doctor who uses these phrases on me as an adult but I feel like they're talking to a kid. If you think about it, those sorts of things above could be used on either quite professionally, apart from maybe the last one.
Very occasionally, depending on the context and how I'm behaving, my mum still calls me ‘kid’ sometimes even though I'm nearly 40 (four months to go!) and she doesn't realise how much I inwardly glow at being called that, right down to how I still remember her laughing at me for riding on a luggage trolly in an airport age 16 and she said ‘You big kid’ while shaking her head. I love phrases like that. Even though I don't recall anyone calling me this, I really like ‘kiddo’ as well. My first name being used by doctors as if trying to make me feel grown up or the centre of attention in a positive way always does it for me, which is partly why I openly use a play name (Alex) for all things kinky online so people can call me it…I actually prefer it to my real name, and add to that how I came to use it because it was my ‘almost-name’ that my parents almost chose but then didn't. I kind of wonder if I would have been the kid I sometimes imagine myself as if they'd gone with that one instead.
Here's a few more phrases just for fun:
‘Okay, what am I doing first? Shall I listen to your heartbeat or do you want to take deep breaths first?’
‘Don’t worry, boys your age get erections all the time.'
‘In a minute I’m going to ask you to take all your clothes off apart from your underpants' followed by my mum saying ‘Give them all to me’ and perhaps also helping me take my shirt off with ‘Arms up’.
As the teen I quite like questions about how active I am, and maybe a compliment during certain parts of the exam about how it shows.
Outside of the medical stuff I quite like ‘Come on, time for bed’ or words to that effect, and stuff relating to being read stories. In the medical setting, that can work well with things like ‘You need to be in your bed until the doctor’s been to see you' or ‘You need to stay on your bed, you’re going to go and have your operation/surgery in a minute.'
Coming around from anaesthesia is also pretty cool, and the associated phrases with taking things slowly and waking up little by little and parents or nurses saying ‘He’s still pretty zoned out' to someone before touching my arm or face and saying ‘Aren’t you? But you're feeling okay?'
