I imagine that a groin shot to anything with male testicals should at least slow down near anything.

Slow down as in "crumpling to the ground in agony" would be a common untrained person's reaction in a non-combat scenario. Even from a softball. Trust me. Of course if it was a war then adrenaline would be flowing and you could better ignore such things, but I still see the pain highly distracting for a couple seconds afterwards, which I guess could be said for breasts. I don't imagine any of my characters having trained getting hit in the groin repeatedly.
