If is "just human nature" why u are so confused?

This was never the way I planned
Not my intention
I got so brave, drink in hand
Lost my discretion
It's not what, I'm used to
Just wanna try you on
I'm curious for you
Caught my attention

I kissed a girl and I liked it
The taste of her cherry chapstick
I kissed a girl just to try it
I hope my boyfriend don't mind it
It felt so wrong
It felt so right
Don't mean I'm in love tonight
I kissed a girl and I liked it
I liked it

No, I don't even know your name
It doesn't matter
Your my experimental game
Just human nature
It's not what good girls do
Not how they should behave
My head gets so confused
Hard to obey

I kissed a girl and I liked it
The taste of her cherry chapstick
I kissed a girl just to try it
I hope my boyfriend don't mind it
It felt so wrong
It felt so right
Don't mean I'm in love tonight
I kissed a girl and I liked it
I liked it

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

I kissed a girl and I liked it
The taste of her cherry chapstick
I kissed a girl just to try it
I hope my boyfriend don't mind it
It felt so wrong
It felt so right
Don't mean I'm in love tonight
I kissed a girl and I liked it
I liked it

I kissed a girl, Kate Perry
