Honestly, when I was new here Nanci made a comment that stuck with me. Cornsnakes can live up to 20 years so you'll have plenty of time to get to know each other. Don't rush him let them settle in.
I was lucky with mine. He was and still is very gentle. Little squirmy at first when he was little but now is pretty much at ease with me handling him. Last night he decided he wanted to crawl up my shorts while laying on the sofa with me and spent all of NCIS there. Of course I couldnt' resist telling my wife to reach down my shorts and grab my snake.
