No, and impossible. They may use too much tongue or sometimes not enough, but that's fine.

No, you can't forget how to kiss. Think about it this way: the first time you kissed it worked even though you had zero experience kissing someone. So why would it not work after a five year pause? Besides, I find kissing is different with pretty much every guy since they all have their different techniques and so you sort of adjust. Hence it's sort of like a continuous learning experience.
