Is it normal that i would never causally hook up with someone?

Is it normal that i hate the idea of causal hook ups. like i would never do something like that, ever. all of my friends are always hooking up with random people at the clubs we go too and honestly i hate going out with them because i just end up alone while they are off hooking up with some random person. then its just awkward for me when i have to reject the people who are trying to hook up with me. the whole thing just makes me uncomfortable. like i wish i could just go into a club to dance and socialise in a friendly manner. i wonder if maybe i am more mature then my friends and maybe in a few years they will feel the same way as me, i don't know but anyways back to the point, is it normal that i feel this way or am i just weird?
