I recently started a sexual relationship with a trans woman(mtf) and I’m not sure how to navigate the dynamics.

I (42 Bi F) recently met a woman on the Her app and after about a week of texting, we met up for a drink and ended up having sex. The thing is, I had no idea she was trans until her dress came off. Nothing about this woman made me think she wasn't afab. Her profile didn't say anything about being trans. She said she was a lesbian. She never mentioned being trans in our conversations leading up to the date or on the date itself. She just let me find out in the moment. Obviously, I was a little taken aback, but I feel like I did an ok job of not coming off as too freaked out or anything. And honestly, the sex was really great! It was hot and passionate and I'm really looking forward to seeing her again. The thing that I'm unsure how to navigate is my role in this dynamic, sexually. I tend to be very submissive when I sleep with men, and very dominant when I sleep with women. I tend to be attracted to very masculine and dominant type men, and very feminine and submissive women. My new partner definitely fits my type in women…very feminine and submissive. I planned the date and was taking the lead the whole time, like I would on any other date with a woman. But once our clothes came off, her whole demeanor flipped. She became very dominant. She was throwing me around the bed, the sex was very rough and very much focused on her penis. It was just all masculine energy and it caught me off guard as that was not what I was expecting. I really like her, and I want to explore more with her sexually, I just feel like I'm in uncharted waters here and I don't want to screw it up. Obviously, I need to talk to her more about this and what she wants out of a sexual relationship with me, I just don't want to sound like a dummy or even worse, say something wrong and offend her. How do I navigate my own uncertainty and ask about dynamics without blowing it? Thanks in advance to anyone with experience or insight here.
