[ELI5] Why does parallel parking only work when reversing at the start?

edit: Thank you all for your explanations. I believe I now have a firm grasp of why reversing is easier to complete a parallel parking maneuver.  Thanks everyone again :)

Because your turning wheels are only at the front of your car. As your back wheels get where they need to be while reversing you can turn your front end in. Otherwise you would need to drive onto the curb or much farther ahead to drag your back wheels into the parking space. It’s not that you can’t do it forwards you just need less space while reversing.
