The first time I was open to a physician was the worst experience of my life in a healthcare setting. I got strep throat like every three months. I went to an urgent care facility, and they started asking me questions about my sexual history.
I didn’t understand why, but I answered them honestly, and as soon as it became apparent that I was gay, they diagnosed me as being HIV-positive, before giving me a strep test or an HIV test.
It’s easy to assume folks won’t respond positively to information you might consider sensitive, but unless you’re giving all of the information you can possibly give, you’re not going to attain the level of success you might need or want.
Come out to your healthcare providers. What they don’t know could hurt you.
