I do feel a sense of discomfort with the term cis in relation to its binary nature. I definitely can't be described as cis and in a conversation where the terms cis and trans are being used I'm always fearful that I'm going to be labelled trans in contrast to cis, where those seem to be the only two options.

If the description is non trans, rather than cis, then I feel there's more space for me in the conversation, as I can imagine multiple ways of not being trans (eg. being cis, being non-binary of some description, being binary and post-transition, etc.).

Personally, I prefer to speak only about the specific facts of the situation and not use terms like cis or trans unless I'm describing someone's self identity. So instead of "as a cis woman" I would say something like "as a woman who's always been correctly identified as female..."
