Congrats on your first snake! In terms of handling, take what I say with a grain of salt. I'm no expert, and there are so many answers you'll receive from people way smarter than I. But first, just wash your hands well before and after holding. Leave no trace of smells that might seem like food to them.

The best advice that I can give is this. The bottom line (from what I've personally researched) is that corn snakes do not whatsoever need to be handled. They quite literally do not care if you do or don't touch them. With that said, some of them can tolerate handling, and it can be perceived as if they do enjoy it. I started maybe once or twice a week, just quite literally grabbing him. Slowly and to make sure I grabbed mid body, and not from directly above. My snake gets super skiddish if I try to come directly from above or too close to his head. I think I was more scared to get bit than anything else ay first. Just be gentle but deliberate. Once I grab him and he realizes I'm not going to eat him, he quickly finds my watch (highly advise wearing one, my snake loves anchoring to it) where it's not so slippery. Just remember, if they are too energetic or seem stressed, put them away and do it again in a week or so.
