First of all, which major-mode are you using comment-region in? I'm surprised because here in C/C++ mode the comments of comment-region already look like //... by default and it has alwas been that way.

You can customize behavior with M-x customize-variable -> comment-style

Hope it helped...

When I currently run this function I get commented out lines that look

Is it possible to configure this to use "C++" style single lnie
comments so they would look

// like
// this
