If you have unprotected sex with strangers without disclosing your status would you then tell your sexual health doctor?

This happened today, and upon revealing that I hadn't used condoms with the people that I'd had sex with most recently, the doctor went into 'stern' mode. I told him that people were having sex with of their own volition and that if they wanted the sex to be unprotected then it was their choice. His response was that they only had a 'real' choice if I told them I was positive. Hmmm...

I didn't wish to continue this line of conversation so asked that we move on.

I know that doctors see it as their job to 'educate' about safer sex, but it irks me that they're peddling the view that it's the one (diagnosed) with HIV that has to take responsibility. And it did make me think I'd probably just lie in future to avoid being lectured.

So, when asked by doctors/nurses, are you inclined to tell them the truth about your condomless encounters, or not?
