I’m extremely happy you have a beautiful relationship with your BP and I’m actually quite interested in how my own snakes will react when I give them a massage later 
But please take in what Crawd said. I can guarantee a lot of the bad stigma around snakes is purely down to people believing they have a emotional bond with their 8ft retic and end up in hospital with broken bones or worse.
We have had a discussion on this in the past on here if you fancy the read:
Individual snake personalities?
BP personalities
“Mean snakes”
