I don't think this song is a sexual thing. Its just that she says "no im never gonna be inside of you" and if its sexual like i dont know, girls can't be inside of guys hahah. I think she means to say that she doesn't want to be inside of him she doesn't want him to understand her, she's playing games. He's saying "i'm never going to see inside of you" because he really won't since she's not letting him. He means "see inside of you" like saying im never going to understand you and love you like he wants to. They obviously have like an attraction for each other in it too but it's not going to be an emotional relationship like he wants, which is odd because it's usually the other way around. He's going to fall and get hurt but she knows that and she's expecting it. I don't know, that's just my interpretation of it :)
