Have lurked for a bit, and this topic made me register!  
  I am a female.  *Love* peeing outdoors ~ much better than doing so indoors and do it when out and about in the wilderness or city (I live in a major urban area, and can still usually find semi-secluded places to go if needed). 
 Not overly concerned about "cleanliness", but non-poisonous leaves and snow can be helpful. 
 Indoors, am doing greywater flushing and have everything set up for my DIY bucket-style composting toilet...will likely start this weekend. 
 Great thread!  Yes, hope it does indeed save some perfectly good drinking water from getting flushed.
