We have a dry compost toilet but expect visitors to pee outside. There's plenty of space and privacy, but I know that many women are uncomfortable with the idea. You get used to it pretty quick when there isn't an alternative though! It's quite possible to keep a bucket for this purpose, but peeing in the bushes is just so much simpler in the long run. By contrast, I've never known a guy visit here who's had a major issue with it. In fact, most of them are quite happy just moving to the nearest boundary and turning their back.
I hate finding used toilet paper lying about, so I insist that it comes back and ends up in either the compost heap or the paper bucket in the compost loo (which gets burnt). Whether some ladies choose to shake instead of using it I have no idea, but personally I prefer to use paper and carry it back for disposal, unless it's an 'emergency' pee and I have none available.
I occasionally have a problem with people repeatedly using the same spot and a smell appearing, but this tends to be the guys causing the problem. They're lazy and tend to use the spot right behind the caravans (yeuch! who wants to pee on their own doorstep?!) or right next to the compost loo. A word followed by a bucket of water sorts the problem and it wouldn't arise in the first place if people used some sense and spread their offerings around.
I've been using the great outdoors for years and my only issue is privacy because we tend to have lots of people around, or the weather. Occasionally we have someone who'll be willing to pee in the compost heaps, but they're sited a little too publicly for most women including me. Actually, it's rare we have a guy who pees there either. I think that is because they feel there's an ick factor involved. We did have a lady who brought a sheewee specifically for the compost heap, but I don't think she used it after an initial experiment. When we build our next compost toilet we'll build one which can deal with pee too.
