I don't really meet anyone to actually role play doctor stuff, but when I jack off about real medical experiences, it is always about exams I had as a kid or teenager. So, my age at the time definitely has something to do with what makes it impactful to me.
I enjoy mixing age-play into my play exams. In the patient role I enjoy playing a shy teenage boy, reluctant to get undressed for the doctor. When I eventually give in and take my top off and my jeans my partner will say "that wasn't so bad, you look a fine young man" and then proceed with the exam, measuring me for height and weight, and then listening to me all over. When she asks me to remove my boxers and examine downstairs she'll comment on how I'm progressing through puberty.I also enjoy playing a younger boy and as I'm listened to asked if I want to have a listen to myself and she places the stethoscope in my ears and places it all over me describing what I'm hearing. All great stuff that really causes me to grow in my boxers. 😊
I guess I am without really thinking about it, or discussing it. I'm usually submissive and when I've been examined by a woman, I've always felt little, even when she and I are the same age. She's always The Adult. When I was examining men (well, very young men, cause we were younger then) they were very very submissive and I was in charge and they seemed to act like boys. I felt older when I was the doctor for them. But I've never said or even thought the term Age-play.
At my age (71), I can project something of a Marcus Welby M. D. image as I'm always older, usually considerably older, than the woman who is my patient. I only examine women, and I specialize in thorough stethoscope exams of lungs and heart, especially heart. My most recent patient was 33. I haven't gotten into age play, but I'd love for my patient to role play a shy middle school or high school girl who needs an athletic physical for school sports or cheerleading.
I had a play patient who shared this theme, and am open to most scenarios. During our initial chats, I would ask questions to learn which aspects and verbal queues she was looking for. All in all, an erotic experience.
I've always fantasised having daddy take me to the doctor and me having to fight him and the doctor cause I don't want to be examined or that I'm sick and daddy has to forcefully take my temperature.
