The singer describes a love that feels endlessly satisfying and, at the same time, impossible to have enough of. He begins by questioning the idea that too much of anything is bad, because repeated closeness has not reduced his desire. As the song develops, his excitement becomes almost bewilderment: he knows how strongly he feels, but cannot explain why.
The central image is being unable to โget enoughโ of someoneโs love. This is not simply about wanting more affection; it suggests that each experience deepens his longing. He says that the more his partner gives, the more he wants. The phrase โblowing my mindโ is an idiom meaning that the experience overwhelms or amazes him, rather than literally affecting his thoughts. His promise to spend the rest of his life keeping her also suggests commitment, not only passion.
The song presents love as joyful but powerful enough to unsettle the singer. His questions about what causes this feelingโhis partnerโs kiss, her sweetness, or something elseโshow that he cannot fully account for it. The intensity may sound like romantic devotion, though the repeated desire could also suggest that he feels swept up in passion. The lyrics do not settle that tension; they emphasize how completely the feeling occupies him.
