31M virgin. dont understand how to kiss

Hey guys need some genuine advice on how to make the first move. I dont understand how to kiss and it's not natural to me. I kissed a few girls and basically it went like this...

girl 1: i opened my mouth and she didnt as was like "are you trying to eat my lips?"

girl 2: i kept my mouth closed this time and i landed inside her mouth

I saw some videos with people kissing and it always make a wet noise. When i try to kiss, i dont hear a wet noise. Mine is more of an airy popping noise if that makes sense. A saw a youtube video where a girl said she got an ick because she dated a guy who when he kissed sounded like a mom kissing her baby. not sure what that means.

Any advice?
