Most urinals I use (the ones at work anyway) have laser sensors that know when you're walking away, and they flush automatically. If I had to flush a urinal, i'd probably use the back of my hand and then wash it thoroughly.

In a stall, I always use my feet, no questions asked.

The other thing I do is after I wash my hands, I dry them with paper towel and then keep the paper towel on my hands when i grab the door handle to exit, and then throw the paper towel away somewhere outside the bathroom. There's a ton of piss on that door handle as well, not to mention the faucets.

I guess at the end of the day you're going to come into some contact with other people's waste matter, but i'd like to limit that as much as possible.
