DOM ca SUB

Hi , so I’m just wondering if anyone has gone through this and can help me with what I should do, so I got into a relationship with a female and I’m also a female , but when I’ve been with guys I’ve always been submissive and I love it , but my gf is also submissive and idk how to be dominant so how can we fix this problem?😅 sometimes she tries to dominate me but than she turns submissive right away. We really never talked about it, so next time I see her we’ll definitely have to talk.
