I'm not a slut!?

Okay, I'm just going to get this off of my chest, maybe it's because I'm tired of people assuming they know who I am and somehow this allows me to let people know that they're mistaken...and part of me what's to know what people really think without actually knowing who I am. I don't have a boyfriend because I don't have time and I haven't really found anyone that deserves my 100% attention but that doesn't mean to say that I cut boys out of my life. I have about four people that I mess around with on and off, they roam in different circles but sometimes I feel that Duke is so small people probably know. I enjoy the excitement of hooking up (yes that includes sex) with these other people and I like the variety, yet, I can't help but feel empty too. Obviously, I'm aware of the double standard, if I were a guy this conversation probably wouldn't even occur to me but I feel like this is more than the "it's not fair that people label as something when I'm just sexually liberated". It's more than that because there is an internal conflict. Am I doomed to just feel like slut? I don't have time for a relationship, but sometimes it wouldn't hurt to have a cuddle buddy when watching a movie but I do love those easy "wanna come over" calls after those late nights. How is it possible that I derive pleasure and even confidence from having different guys want to hook up with me but deep down I can't help but feel kind of slutty. Is it society? Am I in the wrong? confused? lying to myself? all of the above?
