No.
For a number of reasons, the main one being I'm in a committed relationship with my fiance.
But even if I wasn't, there's nothing wrong with a girl enjoying/wanting sex as much as a man. I think being a slut is more about your approach to sex, like, do you pick up randoms for one night stands on a regular basis etc.
A girl should be able to do whatever she wants in the bedroom without fear of being called a slut, as long as she's not engaging in questionable behaviour in public or overly promiscuous I see no problem. And even then, everyone has a different opinion on how many is too many.
