It's just a hiccup you are having, you don't have AA during your initial approach or mid game which is good - so technically you shouldn't really have a problem with going the whole way!..
At the end of the day, Girls want to be kissed.. especially girls that have been on "multiple dates" with you, they are obviously interested and most likely thinking; "why hasn't this guy kissed me yet"..
Try one of Mystery's kiss techniques; (move yourself into a comfortable position obviously) then look at her eyes, then lips and just repeat that, if you get a good vibe from it, take her hand, squeeze it and just go in for the k-close..
Just make sure you smell nice..
