Well Kody, that's pretty rough, and I definitely know how you feel. It's very frustrating to be misgendered, I would know. For the first six to seven months after I started T, I was still consistently called a 'girl,' and a 'she,' However, now that it's been nearly a year, I am very consistently labelled as a male, and I'll tell you a few things.
It's very hard for some people who knew you as a 'girl' to adjust to calling you a 'he,' even if they accept and support you. The truth is that it's just force of habit. Now, I don't know how long you and this woman have known each other or what her relation to you is, but even if you've known each other for just a few years, she's probably known you as a woman longer than she's known you as a 'man,' but obviously, I don't know for sure.
And as far as being feminine goes, that was a huge obstacle for me in the beginning, but once I got on T and my voice started dropping, this changed greatly. Also, remember clothes, hair, mannerisms, and if you need to, binding. One more thing that I will say though, is that being feminine isn't necessarily bad when it comes to passing (Unless being seen as a gay man bothers you, because we all know that everyone thinks your gay when you're a little fem) after all, just look at how feminine some natural born men are. After I realized this and began to embrace that, I really began passing more. Thinking of it gave me confidence and helped me change the way that I move and interact with other men.
Having people call you a male can take a long time, and can be helped by passing, it took me nearly a year to start getting labeled as a guy, but eventually, it'll happen for you too :3 Good luck!
