Anyway I think this works just fine.. :)

Verse 1:
Em          G              Am
This was never the way I planned
     C
Not my intention
Em        G               Am
I got so brave, drink in hand
      C
Lost my discretion
Em           G            Am
It's not what, I'm used to
      C            Em
Just wanna try you on
        G           Am
I'm curi-ous for you
        C
Caught my attention

Chorus:
Em          G                 Am
I kissed a girl and I liked it
                   C
The taste of her cherry chapstick
Em          G                 Am
I kissed a girl just to try it
                C
I hope my boyfriend don't mind it
Em           G
It felt so wrong
            Am
It felt so right
               C
Don't mean I'm in love tonight
Em          G                 Am
I kissed a girl and I liked it     (Hey)
C
    And I liked it

Verse 2:
Em          G               Am
No, I don't even know your name
    C
It doesn't matter, 
Em           G          Am
You're my experimental game
      C
Just human nature, 
Em           G              Am
It's not what, good girls do
     C                 Em
Not how they should behave
            G           Am
My head gets so confused
     C
Hard to obey


Chorus:
Em          G                 Am
I kissed a girl and I liked it
                   C
The taste of her cherry chapstick
Em          G                 Am
I kissed a girl just to try it
                C
I hope my boyfriend don't mind it
Em           G
It felt so wrong
            Am
It felt so right
               C
Don't mean I'm in love tonight
Em          G                 Am
'cause I kissed a girl and I liked it    (Oh Yeah)
C
    And I liked it

Bridge:
Em          G           Am
Us girls we are so magical
                C              Em
Soft skin, red lips, so kissable
           G              Am
Hard to resist so touchable
           C
Too good to deny it
Em            G              Am    C
Ain't no big deal, it's innocent

Chorus:
Em          G                 Am
I kissed a girl and I liked it
                   C
The taste of her cherry chapstick
Em          G                 Am
I kissed a girl just to try it
                C
I hope my boyfriend don't mind it   (Yeah)
Em           G
It felt so wrong
            Am
It felt so right
               C
Don't mean I'm in love tonight
Em          G                 Am
I kissed a girl and I liked it    (Hey)
C                B
    And I liked it
C             B
Yeah I liked it
C          (G   B)   Em
Mmm I liked it
