First kiss?

I'm 17 and have been talking to this guy for a month now. We've gone out together and stuff but idk how to kiss. I'm scared that he's going to not like me after it and I'm scared that he might try something weird too. Idk how to initiate it or anything, any good tips on kissing? Also any comforting things for first kisses would be great 😭😭 bc I am so scared
