It is no secret that many staff of the royals have been are are now gay. They are loyal, discreet and know what they are doing. The royals also return the favour by generous treatment. Most is unnoticed, but Charles in particular is known for coming to the assistance of his staff in times of severe distress.
I imagine Camilla would be much the same. She seems "down to earth" and "live & let live" in her attitude, although she is now restricted in her public statements. Of course, she has no stones to throw at anyone, I do not see her as even thinking about it.
