Am I too confident or not confident enough?

Hey guys, so I'm a 16 year old girl. I'm just trying to figure myself out here, and need some help from you guys. So basically, at parties and stuff, when guys try to grind with me and stuff, I always say no. I honestly can't tell if I'm too confident and feel like I'm too good for them, or if I'm not confident enough to have the decency to dance with a cute guy who wants to dance. The thing is though, is that they don't want to just dance. Like they want to get *** from me. They want to grind up against me and feel my body and everything, and eventually, they want to hook up with me. Let me just say that I'm not imagining this or like making it up in my mind, because I saw all the guys there were trying to get girls to grind with them, and to hook up with them. It just bothers me, that they don't care about me, and don't lie to me and tell me that they do, because they don't. Like it annoys me that the only reason they want to dance with me, is because I have a , , and a mouth. Like that is all they want. C' mon, think about it, what is it that straight guys want most when they go to a club? Very good, you are right. They want to get *** from as many girls as possible. It annoys me that if a guy gets a lot of *** from girls at a party, he is considered "the man", but if a girl grinds with a lot of guys, in my mom, she'd be considered a slut. I know it's just about having fun and stuff and I shouldn't look so deeply into it, but it just bothers me that I am not able to have fun like that. Like yes, I have fun when I'm dancing with my friends, but when they are actually letting the guys do stuff to them, I push all the guys off of me, and maintain my pride and self respect. But like honestly, how much pride and self respect could a person have , and where is the limit. I really need advice from anyone. Please help me, I've asked my friends for advice, but there are all stupid teenagers like me who don't know anything yet. I really need advice from anyone! Guys or girls, it doesn't matter, but I would prefer girls, because obviously guys are gona tell me that yea I should just let them all grind on me and stuff. If I sound really immature about this whole thing, im sorry, its just that im really confused and need some advice please.
