HELP...Boys...too much flirting...?

I am really scared. Too many boys at school think I am ually pleasing when I walk by and stuff. I wear long sleeve clothes and wear jeans. I never expose skin, unless it is really hot and I have to wear a t-shirt. By girl roomate told me that I have a fab body and cute face. This police officer once told me that I look cute that is why boys follow me everywhere and flirt with me. I am scared. Please help How do I stop being "y" or whatever. I just want to go to college and study and get my degree. Sometimes boys talk dirty with me. What do they think, that I'm going to crack and go with them or whatever. They are dumb. That is against my morals and religion. HELP?
