My guess is that because perfumes are mostly alcohol, and that isn't sticky and evaporates quickly. Some essential oils and absolutes are very, very sticky indeed ( oh, the unintentional hilarity of me and mimosa... )
As for sweet things, as I understand that those are effects created by various aromachemicals rather than sugar or honey itself.
Oil-based fragrances are, on the other hand, a little greasy and remain noticeably that way for a while until they're absorbed by skin and clothing. Some are rather sticky.
