First kiss

Alright so I'm 14 years old and I haven't had my first kiss yet. However, my boyfriend says that the next time we meet up ( because he lives fairly far, like a half an hour drive) he wants to kiss me if I'm alright with it. I really want to, but I'm nervous. He said if anything goes wrong we can just pretend it didn't happen and carry on. But what if something goes wrong? What if it's really awkward? I don't even know how to kiss someone. Any tips or advice? Tell me what you think πŸ’—πŸ’—
