I personally don't tell them, I don't feel that it's anyone business. I would never ask a cancer survivor how they got it, or someone with heart disease how they got it.

I tell them when I have lemons, I make an ice cold pitcher of lemonade. There are plenty of research studies done on folks who have undetectable viral loads from taking anti-virals. Those studies show that there is zero % chance of transmitting the virus as long as the medical regimen is followed. I have been undetectable for the past15 years. I still practice safer sex, but it's a relief to know I'm not as contagious as I once thought. Is your partner also poz? If not, it's still important to get tested every 6 months. Also are they on PrEP protocol? That will greatly inhibit their chances of getting HIV. Let me know if you need more feedback on this delicate subject.

I have been living with the virus for over 34 years and I have been asked, by medical professionals in questionnaire and surveys, it depends on the context and how the question is asked, If respectful i don't mind sharing, Education is the key, I have to remember they is still a stigma attached to (Hiv) and it is sad we still have a long way to go especially in the southern states Healthcare is awful and in some areas in its infant stages.

I never am ask only if I wish to tell them you should never be.put in that place by anyone

I was at the Pink Concert in Toronto, I was with my partner and adoptive son. Of course, I got the highly caffeinated hyper on sugar son. In the morning i took the three HIV pills. The discussion was focussed on how long I would be there for them. My partner unlocked the door to the adjoins room thanking me for a restful sleep. ‘I’ve spoken with his doctors in Halifax and it comes down to him having a virus he can’t spread right now so focus on you not us’ Hes an information sponge so looked up the information so he could be supportive.
I’ve openly discussed the journey with only 2 close friends. They had been my support team over my residency in Vancouver.
I don’t stand on soap boxes or play the town crier. My life and heath issues are discussed on a need to know basis.
