I am in the same boat as you; I only received my corns about 1-2 weeks ago.
I make sure not to handle them at least 24-48 hours after they have been fed. Other than that, I make sure to handle them at least once a day. I find that they are normally "sleeping" during the day, so I guess I am waking them up.
As for the wanting to be left alone: I suppose that he'll either put up with it, or take matters into his own hand (erm, scales) and give you a thrashing.
I dunno, but I'm sure someone here will pop in and give some more/better info! :wavey:
