no but the way we talk about it is. we typically use vocabulary to describe orientation that is relative to gender identity. that is, a person who is attracted to men is gay if they identify as a man or straight if they identify as a woman.

that said, "transgender lesbian" shouldn't be too hard to parse unless you've been living under a rock for the last fifteen years.

I didn't know this was really a thing, I've only heard of it on Mad TV when I was younger
