You aren't a puss, you just don't know any better! Lol! Flip the loose jaw over so there's no way to get your hand caught.

You need to go ahead and stick your hand in one so that you know what it feels like and how to get yourself out one handed. If you're too scared to do that then yea you might be a puss! Lol! YOU ARE GOING TO GET CAUGHT IN YOUR OWN TRAP IF YOU SET THEM ENOUGH!....... There's no way you're any more careful than the thousands of other trappers who have caught their hands.
