I don't know how to kiss but I want to tell my boyfriend if I tell him he will brake up with me and am 18

Kissing is just putting lips together, basically. Practice in a mirror. This guy must be pretty shallow if he will break up for this reason.

Are you serious? How long has he been your boyfriend that he does not know you don't know how to kiss?
How old is he?

I don't know how to "eating kiss"

I don't know how to "eating kiss"

Neither do I!

Never heard of "eating kiss" either a local term, or just a term for kissing.

You just try, and it will all work out fine, No need to tell him, when he starts to kiss you, just follow what he does

We always called it "swapping spit" or "lip lock."

U poor baby don't worry Sharni to the rescue. So u haven't had a first kiss yet cool my advice is tell him this will make the kiss more special for u both in a way that,he accomplished something and so have u.GOOD LUCK!!
