I believe Robert A Heinlein has a little “future ad” about a product that allowed women to do the very same thing...
If you have seen some of the service station women’s bathrooms you would not want to sit down on them. Some of the Public Restrooms that are maintained by the government are absolutely HORRIBLE. The last thing you would want to do is to sit down on a feces encrusted public toilet or port-a-john just to urinate.
It is a good thing if this is only used for sanitary purposes, if it is being used just for the shock value or feminist value then that is bad.
