Lyric discussion by Pithikos 

I also think that he says "No, I wanna fall in love with you". The "don't" is never heard and thus there is a very different meaning. He might want to fall in love but he is incompatible to do so. He doesn't want to have sex or any casual relationship with no real feelings so he says "No" to the partner, "I want to fall in love with you" giving out his inner desire to develop feelings as he might be tired of this senseless sex desire.

@Pithikos He very clearly says the word "don't" every single time he says the line...

@Pithikos I think the first and third chorus is "don't wanna." The one in the middle is "wanna." Listen again closely, the don'ts are there, just not always.
