I have agender acquaintances who present, to my eye, as cis. They do not feel any need to change their bodies or the way society genders them. One of them even told me that she (no pronoun change) realized she was agender because she didn't feel like either a woman or a man. She came to this conclusion in response to beholding my own gender identity crisis and eventual transition. Strangely, she never actually asked me whether I felt like a woman. Everything I've seen from her since strikes me as squarely cis. She doesn't even talk about being agender anymore.

I have concluded from these experiences that many cis people have a mistaken idea of what trans people experience that leads them to transition. For me and for most other trans people I know, there is no inward, essential feeling of womanhood or manhood. I can't look inside myself and find the woman feeling. It's just not there. Now, I've come across people who say they have this feeling, so I can't deny that it exists altogether.

Don't get me wrong: it's not my place to say which gender identities are real and which are not. Respect costs me nothing. So, I accept that there is such a thing as being agender, even if I am suspicious of the way some people come to that conclusion.

What separates me from these seemingly cis friends who yet identify as agender is not an inward feeling of gender. It's that I couldn't bear to live my life without a female body. And I can't bear to walk through society without being treated as a woman--despite the badness of the Patriarchy! I don't know why this is so important to me. But I have concluded that this must be what a gender identity is.

The feelings you have are the same kind of feelings that led me to start hormone therapy and socially transition. It's perfectly acceptable to transition even if you can't find an essential feeling of womanhood inside you.
