Hey! Welcome to the forum!
A corn snake was my first snake too
They are awesome beginner snakes, and a little easier than ball pythons. When I got my corn snake,
this book was indispensable. I highly recommend it.
Hopefully you'll find a rescue some place nearby so that you can get a feel for touching snakes. To be honest, when I got my first corn snake, I hadn't even really been around snakes before then. I mean, I'd touched the ball pythons at the local zoo and stuff, but not much else. It'll come pretty naturally to you. Just like when you hold any other live animal, you'll probably naturally hold on to it with gentle pressure and you won't drop it
Good on you to do the research before getting the snake though. You're definitely headed in the right direction! While you wait, you could get the enclosure set up and stuff that way it is all ready by the time your little snake come home.
There are a lot of people with a lot of collective experience and advice on here, so I'm sure you'll find the answers to all your questions
See ya around!
