help, shaving... Options

[cheri_pi]

im 15, in the 9th grade
i dont think my parents are aware that highschool girls shave their legs
my mom never mentioned it to me or bought me a razor or anything
but
its really embarrasing to have hairy legs around the other girls in gym class
so
whenever im home alone i sneak into my parents bathroom and use my mom's (elecric) razor.
however, im not home alone any more than once a week, and i feel bad and and really pitifully loser-like to have to sneak around to shave my legs.
i cant just do it in the house when im NOT alone, because the razor is electric, and everyone can hear it when it's on. once i tried shaving w/ that razor upstairs when the rest of my family was downstairs but my dad heard and came upstairs. he knocked on the bathroom door and i quickly turned the razor off. he was like, "becca, what are you doing?" and i panicked and said "shaving" and he was like "WHAT?!!!" he couldnt believe it and when i finally came out i couldnt even look him in they eye it was sooooo embarrassing.
my parents i think are sorta uncomforable w/ me growing up- it took them a while for my mom to take me bra shpping etc... its always been a tough issue but i really need help...
i know, im a real loser :S
