A woman doesn’t have to be feminine, there are plenty of masc and butch women. Would you feel more comfortable with short hair? There are also other options. Would you feel more comfortable thinking of yourself as a man (men can also be feminine or masculine), or neither, or both?

I didn’t feel comfortable calling myself a woman, but not crossing any gender boundary, I just always preferred “girl”. I didn’t feel mature enough to be a woman until I kinda forced myself to claim that title. With enough use I now feel comfortable referring to myself as a woman.

Titles and gender can be hard. You are allowed to experiment until you find the expression and terminology that suits you. But also, its okay to feel ridiculous, you can grow into feeling comfortable with whichever terminology you want.
