First: You have to build an interdimensional machine that will be able to transport you into Equestria
Secondly: You would have to be lucky enough to get into this Equestria Universe out of all ever expanding never ending universes out there
AND THEN: You will have to face Discord and actually steal Fluttershy from him. A crature that may send you back into your own dimension and make sure that you will never leave it again.
I would think twice and thrice about wanting to hug Fluttershy. I would be content with hugging Derpy.
