I haven't been bitten by either of my BP girls, but I've been bitten a few times by my bullsnake and it really doesn't hurt. As said above, it doesn't feel good, but it's more of a surprise than pain when it happens then a little sore for about 30 minutes. My BPs just don't bite - my older one, Ana Gwyn, is too much of a puppydog sweetheart to even consider it, and even though Tonks was a bit crankier when I got her, I handle her lots (daily, even if just to pick her up for 30 seconds) and now I can't imagine her ever biting me other than by accident. The bullsnake is a baby and still figuring out this whole life thing, and the only times he's bitten me were the day I got him and he was scared, the day I got too close while he had a mouse, and yesterday when I was rearranging his tub and accidentally pinched his tail (and he didn't even get me with his teeth, it was more of a hard nose-boop to say STOP IT). All my fault totally, but none of them hurt at all, just itched for a little bit after.

Honestly, I think that most BPs aren't naturally prone to biting and if you've already had your baby for two weeks and haven't gotten nailed, you're probably not in much danger of it. Just feed with tongs, never stick your hands near them when you smell like prey, and you're probably good. I'm a big proponent of frequent handling, like I said even if just to pick them up for one minute to touch them all over and get them used to being held, which is especially good for headshyness. Also there are some good "snake body language" videos on youtube you can watch to look for the signs. Good luck and don't be scared, at 90g you wouldn't feel a thing anyway!
