Mating Of Leopard Slugs

One may think of slugs as not the most beautiful creatures on Earth... I think this may improve after watching this video... these guys do flourish when they do it! They do not rush about it that's sure for one thing, these slimy bastards! Be aware because beauty lurks at the most unexpected places sometimes, and my sense of it was definitely triggered... what would be the human analogue I wonder?!?
