Well it's obviously about a girl he either can't be with or who doesn't want to commit to him. He's still young enough to get spend time experiencing meaningless relationships - 'I am still young, My blood flowing like a flood, Come and take every single bone, I will give as good as I get' could quite easily be a sexual connotation - but he's saying he's been there, done that, and ready for something more real. It seems like this girl cannot quite bite the bullet and commit to him like he wants to.
