What does different types of kisses mean?

Ok well, to girls kisses mean a lot, they are like the one sign that tells us how much guys like us:

kiss on the lips: something more is going on then your average friendship, and if it's really deep then you've got something
neck: intimacy, something special and sexual
forehead: comfort and just being there
nose: a cute hello
ear: it's leading to sex
and I think if your friend that's a girl kisses you more then once on your first date then she wants to be more then friends and you too feel the same way about her that she feels about you!

hope that helped : )

In my opinion.
the lips. Means she has been waiting for you to kiss her forever and she really likes you.
the neck. She is playful and just wants you really bad.
the forehead. She likes you just as a friend
ear. She is also playful and she just wants to cuddle and make out
nose. Actually that one I'm not sure
stomach and chest. She wants to have sex

Lips (closed mouth) - tenderness, love
Lips (open mouth) - passion, desire
Neck - passion, lust. This is definitely an "I want you" kiss.
Forehead - gentleness, comfort, care, may be non-romantic (I kiss my friends on their foreheads all the time)
Ear - playfulness, somewhat sexual but not overly so
Nose - playfulness, fun. I see this kind of kiss most often with couples who have been together a long time and are very comfortable with each other.
