Didn't Go As Planned

I am attending night school on Tues and Thurs nights to finish a degree I walked away from as a junior in college. In one of my classes there is a trans person. Biological male living as a female. She isn't totally passable, but fem and pretty hot. I have always had the fantasy of being with a trans girl. Over a couple of weeks I chatted with her before and after class. Yesterday, after class, I got up the nerve to ask her out. She gave me a counter proposal that surprised me. She said "I live nearby, why don't you just come over to my place". She meant right then. I quickly said yes.
We barely got in her apartment door when we were making out and pulling each others clothes off. But once we were alone her manner changed. She became very forceful and dominant. I couldn't believe it was happening but in just a few minutes I was on my knees sucking her cock! I spent 30 minutes bent over the arm of a couch gritting my teeth as she broke my virgin ass in. Afterwards she kind of apologized. As we sat on the couch naked she told me that even though she wants to be a girl she still has the function and desires of a horny guy and thats why she prefers to "top". I sat beside her listening and stroking my cock. Finally she reached over and gave me a hand job to finish me. Darn I am sore today! Tomorrow evening I will be face to face with her again. I am pretty much confused about what to do. I wanted to be the alpha male in this thing.
