Never had lesbian sex before...honestly would have no idea what to do?

Hi there! I know this is going to sound like a weird question but I honestly have never had sex before. I am a lesbian and would of course like to have sex with other women but I don't know what I would do.

I have been watching the L Word for ideas...and it seems to me like it's pretty much just a kind of genital to genital rubbing? Does that really make a woman cllmax?

Sorry to be so graphic but I need help!
Thanks,
Meg

p.s. "going down" on a woman kind of grosses me out...not into that at all.. :-/
