I've got an adult male spotted, and I kept a hatchling for awhile too and figured I'd weigh in.

My adult male, Huxley


Came to me as a 5-year-old used for breeding. He hadn't been handled much and he freaked out every time I picked him up. He was genuinely afraid of me and he would flatten out and thrash around to get away. Never bit though. After a few months he learned the routine and he doesn't even fuss when I pick him up anymore. I can lift him up at any moment and put him around my neck. He's calm as any corn snake when you're holding him.
He quickly learned about the feeding container too and he sits and begs for food when I open the top. This is the only time I'm in danger of being bit. If I even get my face too close he'll lunge at me.

He will stop eating during the winter for a few months and it can be hard to get him to start up again. But I found that he can't resist quail chicks.

Here's a little hathling I bought. They don't come out of the egg with manners as you can see.

If she wasn't trying to bite you out of fear, she was trying to eat you. But after a few months she learned better too and became very calm. I sold her though because she didn't keep her nice contrasting pattern. Here she is a little older:
