Every time I see your face
My heart begins to race
I guess it's all right to say
You've got a lovin' biological reaction on me

Don't know what happens to me
But ever time I see you, baby
It's hard to understand
I feel a change in my body

My legs begin to tremble and I can't walk up
My throat becomes dry and I can't talk up
My palms get wet and I can't touch up
And I can't believe

My body temperature begins to rise
My eyes feel like they've been hypnotized
I feel so numb like I'm paralyzed
You do this to me

Every time I see your face
My heart begins to race
I guess it's all right to say
You've got a lovin' biological reaction on me

Every time you come around
My stomach makes a sound
I guess it's all right to say
You've got a lovin' biological reaction on me

My friends they just laugh at me
They don't understand what happens to me
I know I seem like a fool
There's just no way I can play it cool

My legs begin to tremble and I can't walk up
My throat becomes dry and I can't talk up
My palms get wet and I can't touch up
And I can't believe

My body temperature begins to rise
My eyes feel like they've been hypnotized
I feel so numb like I'm paralyzed
You do this to me

Every time I see your face
My heart begins to race
I guess it's all right to say
You've got a lovin' biological reaction on me

Every time you come around
My stomach makes a sound
I guess it's all right to say
You've got a lovin' biological reaction on me

Must be the Frankie be jeans
The way they stick on ya
Must be your thighs when you walk
The way they switch on ya

On the real ma
I'm intimidated by you
I've been with mucho models
They can't compete with you

I all want to do is walk up and talk to you
I all want to do is write up my math for you
But I can't 'cause my body is acting so funny
'Cause you've got a biological reaction on me

Every time I see your face
My heart begins to race
I guess it's all right to say
You've got a lovin' biological reaction on me

Every time you come around
My stomach makes a sound
I guess it's all right to say
You've got a lovin' biological reaction on me

Every time I see your face
My heart begins to race
I guess it's all right to say
You've got a lovin' biological reaction on me

Every time you come around
My stomach makes a sound
I guess it's all right to say
You've got a lovin' biological reaction on me
