I agree. It's definitely about a couple meeting to have sex. And there is a definite love connection as a result.

"This part is old and uninviting. Participants all in black and white."

Here he explains the boredom he's experiencing at the party. It seems like no one is truly having fun, which may not be the case, but since he isn't, he sees everyone in a dull light.

"You enter in full-blown technicolor."

He sees her, and everything immediately brightens. She's the object of his interest. And nothing else is in his sight anymore.

"Nothing is the same after tonight."

I'm guessing that he knew that this was a life-changing moment. It can be like that sometimes. XD

"If the world would fall apart, in a fiction worthy wind, I wouldn't change a thing now that you're here."

He's declaring that she completes him and that he has no regrets. Even if the world ended the next day, he wouldn't care.

"Love is a verb, here in my room."

To love, or even to make love, or, I think, even both. There's a connection, sexual or more.

"You enter and close the door behind you."

Obviously, this is when the lovemaking began. She entered his room.

"Now show me the world as seen from the stars."

He's asking her permission, I think. He compares lovemaking to flying. A good analogy in my opinion. :]

"If only the lights would dim a little. I'm weary of eyes upon my scars."

Either he has a bad track record with relationships that he's tired of being reminded of, or he wishes people would would stop judging his imperfections. Who knows? It seems pretty open-ended. I could go with either.

"Pink tractor beam into your incision."

Sounds like penetration to me. :o

"Head spinning as free as dervishes' whirl."

The sensation has him swimming.

"I came here expecting next to nothing."

Obviously he was looking for this party to be a drag. He expected to be bored out of his mind.

"So thank you for being that kind of girl."

Hmm... Well, it seems self explanatory, but for the sake of analysis, he's thanking her for spending the night with him. It seems as if the experience has enriched his life.

Well, that's my opinion. XD
