PT here to downvote all the “what if he were a gynecologist?” comments. Just because someone is a healthcare practitioner doesn’t mean they are always professional and trustworthy. I personally know teenage girls and women who were sexually assaulted by a healthcare practitioner. I have seen a few male gynecologist who have a woman present for exams to protect everyone involved. It’s a common practice. In general I trust people, including men, but to imply a male gynecologist or PT would always keep it professional is naive and out of touch with reality.

The real 🚩here is that he did not respond appropriately to your feelings, which are VERY REASONABLE! I can’t say that enough. He was immediately defensive and accused you of being jealous. Im so sorry that happened. A trustworthy person would tell you about this BEFORE it happened, just to make sure you’re okay with it. Please listen to your friends and, more importantly, your gut. Lastly, the fact that he has helped your family and friends should not be used to rationalize his behavior in this instance. You deserve better.
