I never even give it a thought. I'm not going to get outed, and even if I did I don't care. How someone random stranger chooses to percieve me makes not one jot of difference to the person I am, and thus has no adverse effect on my life at all. I did not do this for them and their approval, I did it for me. It did it so that I would know with certainty what I am, because in truth nothing else matters.
When I was younger and more newly finished I might have been a bit nervous, but the later experience of traveling the world with a life partner who was very beautiful and attractive, but truly only passed intermittently, put me at my ease, because on many occasions I was able to rescue her because I was often misread by her detractors as the "rather plain, long suffering and loyal cis wife, who had stood by her stunning tans partner" which in the heat of the moment I, of course, always used to its full advantage to calm the situation...
I felt for her, because in her later years she sometimes used to tell me how painful it was, which of course I understood, but at the same time I know she appreciated having me as her reliable safety net.
