Am I stupid?

I'm 19, a junior in college and want a serious relationship. I have never been the hookup type, the friends with benefits type etc. All the guys around me have tried to change my moral compass into being like that but I just can't be and I decided to quit guys who try and do that. It's either you want what I want or i'm staying single. (I respect them enough to not lead them on and let them know I don't want what they are offering) Am I stupid for not wanting to try having these open relationships or friends with benefits situations.. people keep telling me i'm young but idk it's just not me...
