Who can I talk to about masturbation??? My friends are CLUELESS>?

I'm 11... and my friends are mostly 10. I have my period already... and all that junnk. well, i masturbate. I started around Xmas time. when I asked my bestfriend if she masturbated, her response was "What's thatt?" so i just said nvm. then, i asked my other friend if she had ever had an orgasm from masturbating. She replied "orgasm? masturbating? huh? what's that?" so i just dropped the subject. I really want someone to talk to because I feel alone, which is normal I guess, but I want someone to talk to. I don't wanna talk to my mom, because that's awkward, ya'll know wht i mean. thanks (:
