Unexpected Attraction During Training Session

I'm usually very professional during sessions with clients. Today, I was working one-on-one with a new female client in the gym, and for some reason, I found myself becoming physically attracted to her mid-session. We were doing lunges when my eyes caught hers in the mirror, and suddenly there was this intense spark. To be honest, it felt like an electric current running through me, which is completely out of character for me. I tried to shake off these feelings and focus on coaching her form without being distracted by them, but there's no denying what happened, or why I might have been drawn to a client so suddenly.
