Sometimes, taking things slowly can help. The day before the next feeding time, just put your hand in your snake's cage for awhile and let your snake check you out. As long as you don't smell like food, your snake will probably just smell and taste you, feel the warmth of your hand, get curious and try to climb up your arm. This way, your snake is making the first move and won't be alarmed. And you can always take your hand out if you don't feel comfortable. A word of warning, the flicking tongue tickles! And snakes just love to climb inside clothing!
The bite of a 14 inch corn snake barely even draws blood. I get worse wounds from the wild raspberry bushes than from an adult corn snake bite. However, the one (and only - Thank God!) bite I received from one of my 7 ft Redtails is something I wouldn't care to repeat. She didn't get a good grip on my hand, but my "pull-back" reflex response (I've overcome that with the corns) caused one of the boa's teeth to become lodged in a finger joint. It festered for 2 weeks (and hurt like a m#*^@$ !) before the tooth finally worked it's way out. I was on antibiotics for the entire time so the infection stayed very local. And I don't even want to think about what might have happened if I hadn't pulled back. The meer thought of having a snake whose girth is twice that of my upper arm putting "the squeeze" on me isn't very pleasant. I can at least "unwrap" my adult corns with no help.
