質問: キス と 口付け はどう違いますか? キス と 口付け はどう違いますか?
回答: they are same things. when you don't want to address it directly, you say 口づけ instead of saying キス. this is exactly like saying "intercourse" instead of saying "sex". well, not exactly though because 口づけ somehow has a romantic connotation where "intercourse" doesn't. both mean touching lips and lips. neither mean putting the tongue into the mouth nor putting each other's cheeks making kissing sound. french kissing = ディープキス (a deep kiss) bisou doesn't exist in japan.
