confused

i just started dating this girl who knows about my transition but we've been mostly talking and getting to know each other. yesterday i went over to her place and she wanted to try something different. we ended up in a situation where she was the one calling the shots, like a dominatrix thing. it felt weird at first but then i kinda got into it. afterwards though, i feel lost. is this part of being together or just some silly kink? does it mean anything deeper about who i am and what i want? everything feels so uncertain right now.
