Wouldn't that hurt men even more? If they spread legs there are privates and men tend to be sensitive when those are hit.
More than the internal injuries that could be caused by water forcibly entering the vagina? Probably not.
See references of this paper which refer to some specific instances: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC1305204/
Edit: the term is "water skiing enema" for rectally injected water injuries... The worst case scenario is severe lacerations to the vagina wall or a rectal blow out.
