Ive been bitten and wrapped a few times. Honstly it doent hurt much at all. If you have tattoos or piercings, those are more uncomfortable than a bp bite (especially a baby).
I found the hardest part was re establishing that trust for the animal after it bites but thats more of an issue of beimg able to identify the signs of aggression before it happens. Its more like trusting yourself to umderstand the snake. Now if i get snapped at, the first thing on my mimd is "im glad she didnt get me because i would hate to not trust her".
Youll learn it. It doesnt always come naturally but usually itll come with practice, as in all things. Good luck and happy herping!
