Kinda skimmed the other posts but here are my thoughts on the kiss close.
If you know you're good at something, then you won't hesitate to do it. If you're good at basketball, you'll jump into a game and play with anyone, and know that you'll have fun. Same goes for kissing. If you're good at kissing, then you'll jump into a makeout with anyone, knowing that you will have fun.
I think your problem is that you don't think of yourself as a good kisser. If you thought to yourself "I am an awesome kisser and girls like to make out with me." chances are you'll actually go for the kiss.
The only reason you're not kiss closing is because you don't go for the kiss. Simple as that.
