Jan, I just have one question: why?
As a teenager I worked in a local marine mammal park where they trained and performed shows with dolphins, sea lions, seals, walruses, etc.
Sea lions come in a lot of different sizes and flavours, besides a show with the biggest and most dangerous Stellar sea lions performed with the trainers safely behind an electric fence they also did a rather funny kids show with the smaller and much more docile Californian sea lions, kissing their trainers was part of the act.
When cleaning up after a show I was alone in the theatre and watched them play while standing on the edge of their basin when one of them approached me, I stood my ground and received a kiss on the mouth as a reward. When they kiss they make a very loud kissing sound so public can here it, they smell very fishy and their whiskers wrap around your face making it a very immersive experience I will never forget
A few days later I tried it again with an other sea lion btw, she approached me like the other one did but instead of kissing me she decided to start barking a few inches from my face, the instant loud noise combined with the small pieces of fish flying around in my face made me almost shit my pants hahahaha.
