Its natural, yeah. Espically when your in junior high. When I was in Junior High, all the guys were already talking about sex and everything, and how they liked it shaved, so I'm guessing maybe the guys are the same there, and hearing them makes you want to shave.
I still havent told my mom about me shaving. I mean, its not really any of your moms buisness what you shave or not. It's yours.
