Perhaps the ladies in the MtF forum might be able to answer this one better than we can?
Anyway, a good start is to spend some time observing the way women in your society act and behave. Sit down somewhere where a lot of people hang out, such as a coffee shop, a shopping mall, or a park bench, and spend some time simply watching how they do what they do. Eavesdrop on their conversations to find out what subjects they talk about, and how they talk about them. Pay attention to their tone of voice and facial expressions. What do women call each other in your society? What do they call men? etc. etc.
