She seems less kinky?

Ok so i have been talking to this girl since march. we are getting a little serious. Anyway in the beginning she seemed more freakier and kinkier in bed. and she seemed that she wanted it more too. now sex is more me taking over and us making love kind of. she doesn't really say the things she use to and doesnt really do anything either. she use to ask me what my fantasies are and stuff.. do you think because she likes me more she is more stand offish on what she does in the bed so she doesnt scare me away or something? i am a freak so i like it all lol.
