While this kind of move can certainly seal the deal, it can also rock the boat a little too much too soon.Now, I have exactly one argument in favor of kissing a girl goodnight on the first date: It shows a girl you like her and if she feels the same way, things might take off from there.Sure, I might get invited in, or have the opportunity to invite my date in, but most likely I'll have to kiss her goodnight outside her place or wherever we are.And I don't like doing that, even with a serious girlfriend.
Maybe do the hug/kiss on the cheek combo, but don't go all out for the deep kiss.
So, go ahead and kiss her during your first date or the second one.
If you do not even try to go for the kiss on your second date, the chick may think you are weak guy and a nice friend. She may even call you once in a while or go out with you when she has nothing else to do. Do not be shy, even if she rejects your or gives you her cheek, you get valuable information and stop wasting your time and money on her.
But here are the many reasons I refrain from kissing a girl goodnight on the first date or dates early on in the relationship: I haven't done the drunk kiss on the dance floor in a long time.
If we don't share a history together, usually a kiss is a meaningless or empty experience.
