I especially refer to girls around the high school age. I've seen a lot of my female friends pee their pants when in high school. A few times when they held it for too long but in most cases due to laughing. Laughter or giggles seem to make lot of girls and young women lose control over their bladders. Never seen it happen to a guy. I'm not saying it happens to all girls but to a lot of them. Why is that? Is it simply because girls have weaker bladders?
