Hidden Desires Revealed

I've been keeping a secret from everyone for months now. As a personal trainer, I pride myself on being professional and disciplined. But lately, I've found myself drawn to something darker, something that scares me. I recently started exploring a dynamic with a client where we played out a teacher-student scenario in private. It's all consensual, but it feels wrong somehow. I'm ashamed of these desires, especially since they're so different from who I think I should be as an adult professional.
