I think he's talking about having feelings for multiple people. Six different ways different people attract him. He feels something for all of them, they each think they are the only one. "They think I'm on my hands and head" "They know I'll give the world and more" --each person feels like they're being worshiped by him (ie on hands and head), but this time they are much too slow. They don't understand he likes them all for different reasons, they aren't the only person he's with.
