Why do i feel the need to use my body?

i don't know how to get a guys attention so i always end up trying to use my body. i'm not the most beautiful girl in the world but i'm not ugly. i'm not fat, i've got long pretty hair, i think i'm ok looking...but i know i'm not gorgeous. i try to wear low cut shirts, short shorts, skimpy clothes, anything i can to make a guy look at me. even if they are looking at my body not my face. i want to learn how to get a guys attention and this is how i do it. i look at my mom, she wore a T-shirt and jeans or long shorts to school every day. NEVER wore low cut shirts, short shorts, or skimpy clothing. even when she went to the pool, never wore a bikini, always wore a full piece. and all the guys liked her and wanted to get with her. i want to be able to get A guy's attention without my body...
