sexed up

Could you please tell me the meaning of "sexed up" ?
In this Robin Williams's song

Why don't we break up?
There's nothing left to say
I've got my eyes shut
Praying they won't stray
And when I'm sexed up
That's what makes the difference today
I hope you blow away

I believe the musician's name is Robbie Williams. The song "Sexed Up" is on Escapology, and there are two versions to the chorus:

Version 1
Why don't we break up ?
There's nothing left to say
I've got my eyes shut, praying they won't stray
and we're not sexed up
That's what makes the difference today
I hope you blow away

Version 2
Why don't we break up ?
There's nothing left to say
I've got my eyes shut, praying they won't stray
Oh! When I am sexed up
That's what makes the difference today
I hope you blow away

'we're not sexed up' means, we are not attracted to each other anymore, and 'Oh! I am sexed up', means I am attracted to someone else now.
