My question would be - what was the motive for the Dr asking so many questions?
As
@Northern Star Girl pointed out, perhaps they were fishing for confirmation of what they were suspecting.
In reality, the Dr should have left it at one question and not pushed any further.
Do you know if your Dr and the practice are LGBTQIA+ friendly?
Here in Australia, we have Dr / Patient confidentiality and by law, Dr's are forbidden to disclose any information regarding their patients without their consent so anything that is discussed with your Dr or staff is held in strict confidence.
Perhaps searching for another GP that is more within alignment of your medical needs would alleviate some of the stress and concerns you might be having.
You shouldn't have to make up stories to appease your Dr.
Blessed Be.
