Hello britt-tapia:

Hopefully it has not happened since then? Did you get some help to "unwind" that event for you? As others have said the groin strikes are not intended to be a "one shot" kill... few techniques do so. However all it takes is ONE, at the right time to connect well and the fight is over.

Women do not want to be hit or struck in the groin any more than any man. The region is nerve rich, and very sensitive. However, if you want to stop a woman akin to the male "groin strike" their chest might be a decent parallel target...
