My Secret From Med School

I've been trying to keep this from my wife for years now. When I was in med school, there was an older woman who would come into the clinic regularly. She had a unique way of flirting with me that was both playful and seductive. It started innocently enough, but as time went on, she began asking me about intimate medical procedures and treatments in ways that were unmistakably sexual. One day, we finally crossed a line when I was alone in an exam room. We ended up engaging in activities that were completely inappropriate for a doctor-patient relationship. Even though it's been years since then, every time I see her now or hear about her from my colleagues, it reminds me of how far I've fallen from what should have been professional boundaries. It haunts me and keeps me awake at night.
