Why are reactions to groin kicks in movies exaggerated?

Because I was watching a movie with my sister and my boyfriend. And we saw the good guy get kicked by a bitch and I was just yelling "get up and fight" 😁
I raged they made him stay to the floor 🤬 It was so unrealistic because he was strong and handsome 😍
My sister said it unfortunately was realistic reaction so we asked my boyfriend 😂.
He said he wouldn't react that way, it is truly exaggerated but he didn't know why 🤷‍♀️

So why? why did they made it so bad for the good guy? 😭
