Lyric discussion by TheTense 

I don't think the song is entirely about losing his virginity, but I do think its a key part of the song. I think its just a little more general.

He's an outsider, "always the new kid". He got head-over-heels in love with this girl and it filled that hole in him, he felt for the first time like he belonged. He wants to stay in love, because of how good it makes him feel. At age 16 he's inexperienced and therefor nervous (remember your first couple of dates - firsts are always scary). He doesn't wanna screw this up. The FIRST refrain (but my heart...) is about his nervousness and how things are going too fast and in general losing his love he craves or more specifically losing his virginity. She cheated on him had he known she wouldn't be faithful he could have avoided this pain (if I knew, she wasn't true). The SECOND refrain (but my heart...) is about his overwhelming sadness and quivering in anguish and how she hurt him after the breakup. The long "woooing" is supposed to resemble crying. BAM.
