I think that your BP can sense your anxiety and thus bites you, while your husband is probably not concerned about being bitten.
Snakes can sense nervousness in ppl very well. You should try to relax before handling and when you approach your BP don't think about being bitten.
Well that would be my advice, but I'm no expert on BP's in any way.
Good luck with him, and I hope you won't have to give him away.
P.S.: I saw Keyboard Warrior's post just after I posted mine.I agree with you Key. Warrior.
