I've heard it said that psychotherapy is what happens when you put two people in a room together and tell them not have sex.

On occasion, sexual energy and tension is just a fact of life. Therapy may be a sex free zone, but it can still be sexual.

That's why the frame exists. That's why it's so important to stay in it. It creates a safe place for those feelings to exist.

I see no harm in flirting, especially if it's acknowledged and talked about.
