Not at all dear. Which begs the question, why would you think so? Obviously something has made you feel that way. If it is, guys not approaching you or showing interest, intimidation is a possibility, along with many others. If it's guys telling you you're ugly, take it with a grain of salt. People are (_o_)s at times, and you shouldn't let those peoples opinions cloud the reality of a situation, in this case, the reality that you are very pretty.
You're adorable.. I always felt awkward as a teenager too- really insecure. It fades with time. My mom would always tell me "..don't let the turkey's get you down" Makes no kinda sense but it helped! Haha.. I want to get my lip pierced too- so cute :)
