Guys: What do you think of tall girls? intimidating? or no?

I am very tall for my age and my legs are very long but i HATE being tall, or taller then most of my grade. I feel so giant and that the guys are scared of me or something. Im so insecure about my height and sometimes i feel like i have to sit down all the time to avoid that. I am 15 years old and 5"8 and if you dont think thats tall, it is. Compared to alot of the people im around I am tall for a girl, I mean i have a nice body dont get me wrong but i would trade that just to be short.. what do yout hink of tall girls?
