What is the meaning of a kiss?

What does it mean? That they find you attractive, and either due to shyness, or concern over how you'll react, they haven't just kissed you spontaneously yet.

He probably didn't kiss you then either because there was no good 'moment' for it, or perhaps because he's having a hard time summoning the nerve to kiss you outright, and wanted to steel himself a bit. He may also be just as unsure of your feelings as you are of his, and was testing the waters (and giving you a chance to object) with a text.

To the third question, given that he's dating you, and is interested in further physical contact with you, I'd wager he's finds you attractive in that way (whether he will act on it/lead you toward it aside. )

If you reply with something flirty and open to being kissed, I'd bet he will on your next date.

Yea he's probably just a little shy, he also is most likely REALLY into you, and wants to take it up to the next level. At least that's how it is for me =) So if he is a little hesitant, just make the first move, guys kind of stress about things like that, he's probably pacing right now ;)
(He probably trusts you too, by the description. )
Hope I helped!

I bet he's shy about the subject and when he texted you he wanted to hint to you that he's most likely going to kiss you on the next date. If he's still shy on the next date then kiss him first when that right moment comes up when you look into his eyes or when he is about to hug you again. He'll be surprised by the kiss but after that one time, I'm sure he will have no trouble making the first move the next time he gets the chance to kiss you. Guys are wired that way. I still don't get it myself.

I understand your confusion. I am kind of going through the same thing right now. He says he wants to kiss me and we are not officially dating. I plan of talking to him nicely and telling him I am confused. And that I do not know if he likes me or not and if what he says means something else or if it means just what he said.

He likes you, but isn't sure how far to go with you and wants to check with you before he tries anything that'll make you feel awkward.

He's probably just a bit shy, and wants to make sure you know he's into you, but is trying to be respectful at the same time. It's a good thing! Spontaneity is great, but this early, it's nice that he's not the type of person to just take what he wants without thinking it through. It's definitely an open invitation for you to kiss him on your next date - it's obviously going to go over well.
