I remember seeing some B movie about a group of women mercenaries who have to stop this white slavery ring. There are a couple of good kicks to the balls in it, and a scene that (while not showing it exactly) looks like one woman shoots a guy in the nuts.
Near the end, there is a scene where a woman is passionately kissing one of the bad guys, and then she quietly pulls out a knife and stabs it deep into his genitals.
I just liked the idea of a woman kissing and distracting the guy by letting him think he's going to get some, and then putting the gun down the front of his pants and firing away. It might have the added bonus of the kissing getting him hard which means that maybe his dick would be shot off as well. :-)
She would then just walk away and leave him.
