I don't think the kissing is significant to the meaning of the song; it's simply about the obsession one person has for another. Perhaps to the other the kiss is simply a kiss, but for our narrator, it makes them fall even deeper into love -or just obsession. The other person can't be "touched" or "hurt" because they simply aren't affected by the contact between the two of them.
I just found this song. It's fantastic!!
