I'm attracted anatomically
Need to know you scientifically
Strange confusion has come over me
Need the fusion between you and me
Mother Nature's legislature, Mother Nature takes her course
Gravitation of the nation, Gravitation to the source
I'm distracted biologically
My attention dominating me
I'm a victim of Divine design
I'm a victim of a one-track mind
Gut reaction, satisfaction, Gut reaction's never lie
Need I mention my intention, Do I need an alibi
It happens every time you're next to me, Biology
Oh oh oh oh oh oh oh oh uh oh, Biology I'm defenseless, lacking all control
It's relentless, longing of my soul
I am driven, I'm completely yours
It's a given, I'll be back for more
It's instinctive, so distinctive, and on that you may depend
Don't go mess with Mother Nature, she'll defeat you in the end
It happens every time you're next to me, Biology
Oh oh oh oh oh oh oh oh uh oh, Biology
Need I mention my intention, Are you willing to supply
Gut reaction, Satisfaction, Gut reaction's never lie
It happens every time you're next to me, Biology
Oh oh oh oh oh oh oh oh uh oh, Biology
