This song is about a girl who would like  to be a boy for one day, because she needs to understand how they feel. Featuring Kelly.

But this is the boy version and he gives also his point of view.

Intimacy, Honesty, Commitment, You, Me, Us

If I were a boy
Even just for a day
I'd roll out of bed in the morning
And throw on what I wanted then go
Drink beer with the guys
And chase after girls
I'd kick it with who I wanted
And I'd never get confronted for it
Coz they'd stick up for me

If I were a boy
I think I could understand
How it feels to love a girl
I swear I'd be a better man
I'd listen to her
'Coz I know how it hurts
When you lose the one you wanted
'Coz he's taken you for granted
And everything you had got destroyed

If you were a boy
Then, girl, you'd understand
You need to stop listenin' to your friends
Love, respect, and trust your man
So I go to clubs with the guys
And sometimes flirt with the girls
I should be able to roll out
As long as I'm comin' home to you
And give you the world

But you're not a boy
So you don't have a clue
How I work and pay the bills
How everything I do is for you

I'd listen to her
'Coz I know how it hurts
When you lose the one you wanted
'Coz he's taken you for granted
And everything you had got destroyed

If I were a boy
(If I were a girl)
I would turn off my phone
(I wouldn't play games)
Tell everyone it's broken
So they'd think that I was sleeping alone
(girl you that's wrong)
I'd put myself first
And make the rules as I go
'Coz I know that she'd be faithful
Waiting for me to come home, to come home

But you're not a boy
So you can't understand
You are not a perfect woman
And I am not a perfect man

I'd listen to her
'Coz I know how it hurts
(and I know how you feel)
When you lose the one you wanted
'Coz he's taken you for granted
And everything you had got destroyed (said I'm sorry)

It's a little too late for you to come back

But I can't let you go, 'coz I'm too attached
If you thought I would wait for you
You thought wrong

No, no
But you're just a boy....
