I'm attracted anatomically   Need to know you scientifically   Strange confusion has come over me   Need the fusion between you and me      Mother Natures 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 reactions 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   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   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 reactions never lie      It happens every time you're next to me, biology   Oh oh oh oh oh oh oh oh uh oh, biology   It happens every time you're next to me, biology   Oh oh oh oh oh oh oh oh uh oh, biology
