A guy getting pleasure from buying me things??

So some from online wants to allow me to online shop using his money. This is exactly what he said "I think it'd be fun to allow someone else to control my finances and put me on a strict budget." 
So he asked if I have an Amazon wish list
But like is this bullshit or do people actually like doing this? And if I do this through Amazon there's no way he can get any personal info of me right?
