As the others have said, let your snake acclimate before doing any more handling. As a first time keeper it's important to trust experienced keepers.

Let your snake settle in for a while, not 48 hours. I highly suggest holding off on handling until your snake has eaten three consecutive meals without refusal.

BPs can be very finicky eaters and get stressed easily. You have 25+ years to handle your snake. Let it acclimate. Your snakes health should be prioritized over your desire to handle an animal that doesn't want to be handled in the first place.
