It's hard. It's something I struggled with for a long time. It felt like I had finally got to the point where I could accept and celebrate my queer identity, only to effectively lose it a couple of years later.
I'm panromantic, but heterosexual, and for a long time, I used the labels straight and transhet, as a way of trying to push back against the whole "a guy dating a trans woman is gay" thing, but eventually, I let go of the label, because I just couldn't deal with the assumptions people made about my queerness. These days I just call myself queer.
Similarly, I felt invisible when I was out in public with my boyfriend. We both just looked like a regular cishet couple. I'd spent most of my life telling myself that's what I wanted, only to discover it really isn't what I wanted, because it erased another part of me that was important. It felt like stepping out of one closet and in to another.
Unfortunately, I don't know what the answer is. At the moment, I'm in a poly relationship with another woman and an enby, so my queerness is right there on display, but when I was in mono relationships with men, it was hard to lose it.
