Doctor's Secret Kink

I'm Dr. Emily Carter, a practicing physician, but there’s something I've been keeping from everyone, my kink as a Mommy in Dominant/submissive dynamics. My partner is younger than me, and we indulge in this adult fantasy where he acts like my son. It started recently, when he confessed his desire for this role-play to me during a particularly vulnerable moment of intimacy. We’ve only tried it a few times but the way he looks at me with such innocence and dependence makes me feel powerful and nurturing all at once. I worry sometimes that I might be crossing professional boundaries in my personal life, especially given the emotional intensity involved. Is it okay to indulge in these fantasies as long as we’re both consenting adults? What if this spills into our real-life relationship, should I be concerned about it influencing how I treat him medically? Can anyone offer advice on balancing a kink like this with professionalism and emotional health?
