This is such a fun song. Despite it's let's-forget-what-went-wrong-b/c-you're-hot-and-I-gotta-have-you theme, I really like it.
The song is obviously about a couple who didn't work out. They were catching up and started to forget what split them up to begin with. (This is a common problem with old flames. The past always looks better later.)

I'm torn about what actually brings them together. Is it that he really did miss her or that she is just super hot? Because it almost seems like he's saying he's crazy about her because she turns him on, but at the same time, he wants to see her every morning from now on. That has to be because she makes him happy, which is the one of the most important things in a relationship. Right...?
