Yeah, I can get pee-shy. Not even around other people, just in a one-holer (single stall) bathroom. I realized that, for me, it only happens if I'm wearing pants and it's because I'm paranoid I've not positioned my STP quite right and it'll leak. Solution? Pull pants down, then use STP. There's something about this arrangement that makes me less afraid I'll leak all over before I realize it. Yeah, it kind of defeats the ease of standing up and won't work in multiple-urinal bathrooms (where I imagine pulling ones pants down to the knees to pee would be odd behavior). But I figure once I'm more practiced at positioning the STP I'll be more confident that it won't leak, thus eliminating the pee-shyness. Or so I hope.
