Dr. Jane's Dilemma: Adult Roleplay in a Medical Setting?

I'm Dr. Jane, an adult Mommy figure to my partner, Alex. We've been together for over two years and our dynamic includes elements of Daddy Domination and Mommy Domination role-play. As his Mommy, I guide him through scenarios that include a blend of nurturing, discipline, and playful authority dynamics. Recently, we began incorporating elements of our daily lives into these sessions to keep the experience fresh and intimate. Last week, Alex had a medical check-up that required some invasive tests. The process was routine but quite uncomfortable for him, and as his partner and caregiver, I felt compelled to offer support. After the appointment, it occurred to me that perhaps being present during such procedures might help ease his anxiety. As an added twist to our role-play, I suggested he view me not just as his partner, but also as someone who understands and can alleviate fears associated with medical situations by combining comfort and authority. I've never done anything like this before, using my professional background in a consensual adult relationship context. However, the idea of combining my expertise with our play felt exhilarating yet daunting. Would it be crossing lines? Could there be potential for Alex to misinterpret my actions during medical appointments as part of his role-play or as an actual doctor-patient dynamic? I'm seeking advice from others who might have experience or insights into blending personal and professional boundaries in consensual adult role-play scenarios. Is this something that could be considered healthy, adventurous, but still respectful to all parties involved? Should I consider limiting such activities to our own space outside of a medical context altogether? Your thoughts would mean the world to me.
