I would be willing, but I don't think I'd go out of my way to do it.
Now, poster below, please consider the following information before you make your decision.
The mouthparts of the ant are arranged in three tiers: The mandibles, a pair of sharp, rigid shards of chitin used for initial mastication; the maxillae, a sort of covering for the inner mouthparts equipped with a pair of feelers; and the labium, small but sharp mouthparts that help bring things deeper into the oral cavity. To kiss an ant on the mandibles would be to kiss them on the cheek; on the maxillae, to kiss them on the lips; and on the labium, to kiss them with tongue. (Lewd!)
Please keep these anatomical details in mind as you consider whether or not you would kiss an ant.
