Nice post. Here's a suggestion, though. Why don't you just take the aisle seat on the bus? Then when a stranger wants the window seat you can just stand up and let him or her pass. You could stand up again when he or she wants to get off. They will never be exposed to your crotch and you get to make the choice whether you're interested in a close encounter with their privates or not. It's a win-win, plus you get all that good standing and sitting exercise that you miss when you skip church (for Sunday brunch).
