Can a girl enjoy hook ups and not be easy at the same time?

in my opinion, being easy means throwing yourself at any guy you see, letting them treat you anyway they want, wearing slutty clothes to get attention, basically giving them the ish without respect. and my definition of hooking up is making out. the only reason i enjoy them is because i feel like i get bored of any relationship after a month, which is pathetic i know, so i just stick to hook ups because i feel like you could have more fun and be less serious, and it's much easier for me to mess up in a relationship, so i'd rather not be in one, and at this age, i feel like i'm not really ready for a serious relationship where both partners are insightful towards eachother. what do you think?
