Idk about Freud, but I still think (mouth-to-mouth) kissing is weird and if I could get away with never doing it again I would. It just squicks me out and I always feel awkward. Kisses on the cheek/forehead/crown can be tender and on the rest of the body can be really sensual, though. But hugs > kisses every day of the week, romantically and platonically.
