<human>: Can you succinctly summarize the text in 1-3 sentences?

So I'll give you a little background on this:

I'm 17 and for the last few weeks I've been seeing this girl (went to out with her for some drinks and stuff).She is 16 and I like her really much and I am open when it comes to talking but when I should say goodbye to her or when we meet up and should hug/kiss on the cheek I just cringe or something and go weird mode. Even when I see her outside with her friends I don't come up to her to say hi I just wave my hand like some sort of a wuss. Can someone give me some advice how to overcome this problem
<bot>: Find it hard to hug/kiss on the cheek this girl I'm seeing - when we meet up or part ways I cringe and go to the weird mode. Advice to overcoming this problem please.
