Acknowledging a New Side

I've been training clients at the gym for years, maintaining my professional persona. Recently, I realized something about myself that's both surprising and unsettling. During sessions with some of my younger female clients, there's an undeniable pull towards DDLG dynamics, a desire to guide them more authoritatively than professionally necessary, even feeling compelled to play the role of an older authority figure in a sexual context. This has never happened before; it feels isolating. Is this kind of shift common? Should I seek therapy, or is there a community that understands this side of me?
