Being a poz woman, I get a lot of stigma from hetero men, and ignorance from hetero women. I pick and choose in whom I confide, but because of how my story was made public, I never had, what I perceive as a luxury, privacy. So I’m out, so to speak. I wear a red ribbon on my jacket, and I’m honest. I hope my honesty and openness can be used as a teaching moment, and a stigma busting moment as well.

I do not deal with stigma. If people treat me like a pariah because I am poz,they are not worth the bother.

I agree with Xavier. Being HIV+ is a part of your truth. You do not have to share it with everyone. And, whom you share with, there should be a mutual trust between you.
It's the situation that can determine.
My three closest friends were the first to know and they proved themselves true, no change, except maybe a bit more love shown by caring about my health.
Then there was my roommate who I did not tell, but he broke boundaries and looked in me medicine cabinet, found my medication, looked it up on line and freaked that I hadn't told him, he was afraid. The next day he apologized. He studied online and it eased his fear, but trust was lost.
My sister was the first family member I told, she cried. We talked for hours. We grew closer together than ever before.
Then there was the first 'hookup', I told him online and it was stated in my bio that I was HIV+. But when he tried to enter me bareback I told him again, he just dressed, left and blocked me.
All my family and friends know now. And I speak in front of College biology students when asked. This experience let me know how little the majority know about HIV and how open they can be with wanting to understand them.
It can be uncomfortable to share. Trust your gut with whom you share. Stigma exists because of ignorance.

That is all anyone can do, be honest with yourself and to those you care about and don't let stigma get in your way as we only have one life to live.

I just ignore it if people don't want to know it's there loss because I'm a great guy
