25FEMALE, I feel pretty insecure and awkward about my body. Is there a FEMALE who relates and can lend an ear?

I was just wondering, am I the only one who feels really insecure and awkward about my body? I'm about 5'3" tall and have a slim average upper body, but I've got a BIG ASS (I HATE IT). I really hate the unwanted creepy stares I get, especially when I wear tight clothes, and I don't want to be sexualized or recognized for just one part of my body. On top of that, a few bad experiences in the past have made me feel pretty timid everywhere. Plus, I'm not the kind of person who likes to show off my assets to everyone.
