I don't want a relationship but i don't know why.?

I'm 17 years old. I know that's fairly young. Everyone in my circle of friends has a special someone but I don't feel like i want one. It's not that i have a hard time finding guys. I definitely don't. Every time a guy likes me and we start to talk he never leaves me alone. I feel smothered and I tell them but they don't understand. When i see cute movies and hear cute songs I wish that i had a special relationship but what makes me stop is the getting to know each other part because it takes forever and both people are just telling the other person what they want to hear. Another problem with guys I meet is that they talk to me as a potential girlfriend instead of as a friend. So right off the bat they're cheesy and not really interested in me but the idea of me. Basically I want to want to fall in love because I honestly don't see the point. What should i do?
