To be good at dating girls takes practice like everything else.
Its not that people are born with this trait. like in sports, in order to become better you need to practice it every day or atleast every week in order to become better or even just to keep yourself at your current level.
Trust me on this. On the first dates you will have hard time finding interesting things to say or you will not know how to escalate things on the sexual level but in time as you go to more and more dates it will grow your "dating muscle" :) and things will start getting more natural and this is your actual goal if you think about it - to be and feel natural around girls and even beautiful girls.
But like in sports to have a personal trainer or a couch is not a bad thing and this is why I want to reccomend a couple of youtube channels that are specialized in this kind of material:
