HOW DO YOU KISS (every detail pls)

Guys please help I have no clue how to kiss and honostly the sound of slobbering on someones lips sounds disgusting and tongue on tongue!! Maybe I'm just immature and havent had a REAL kiss yet but I saw this girl on tiktok say you have to choose either a top or bottom lip but isn't that uncomfortable and nasty I dont think I'd enjoy that at all. Please share your experiences with kissing and what you did and don't leave out any details!!!
