If he's out already that's the perfect time to reach in there and pick him up. Night time is when I do all of my handling, and with the exception of if I'm doing big enclosure cleanings when the snake just has to come out, I try never to pull hides and pick them up during the day. Slow deliberate movements, support his body but try not to touch his head or tail, and be gentle with him. Time will make him a little more comfortable being held, but you can't rush it, he'll get comfortable on his own time not yours.
