I tried one of those Freshette things a couple of years ago. I discovered that I had to pull my slacks and underpants down anyway (evidently this gizmo requires a fly front and either those awful bikini-style panties or fly-front men's briefs. Then I ended up with pee all down my legs and pants anyway. Forget it; I'd far rather have a few mosquito bites on my bottom.
