I’m a lefty, but it is all very specific to every task.
Writing, throwing a baseball or football I do lefty and can’t do well righty.
Golf, hockey, bowling, frisbee I do right handed and can’t do it well lefty.
Throwing darts, shooting a basketball and random other stuff I’m fairly ambidextrous.
When I picked up a guitar/bass for the first time right handed felt natural and left handed felt awful. So for me it never usually comes down to which way I want to learn something, one way just makes more sense to me and feels way better than the other.
