Yoh we have a live one tonight!
Just remember like any thread no matter the topic some posts are in jest...
Me personally I see the issue but not that it's an issue of one gender not considering the needs of the other. Festivals are disgusting when it comes to any sanitary needs, it is what it is.
Taking a dump in the porta potty on day 3 of a festival

Why can't the tampons or pads be changed in a tent, you'll have your water and soap on hand or wet wipes will do just fine and job done in the privacy, cleanliness and safety of your tent?
