This song in essence screams woman in an, perhaps, unhappy relationship who is cheating and torturing the poor soul of the mean she's cheating with. He knows she has someone else but he wants her all to himself, and doesn't want "love" on her terms, where she can break the relationship on a whim. He wants all of her but can't have her, hence "love bites", although he still craves it. He doesn't want to make love to her, much less touch her, for fear of falling for her more, only in turn, to be shut down by her when she sees fit. She seems to be unattached, whilst he can't help himself.
