I don't really know what it feels like, it's just kind of there.. I don't pay any more attention to it than I do to say my pinky toe. (Until it screams into my ear with a megaphone once a month.) But to comment on getting kicked down there, I haven't experienced that per say - but I've slammed down legs on either side of a metal bar quite a few times (usually biking accidents) and that left me rolling around on the ground holding myself for a good few minutes then walking funny the rest of the day. Ouch.
