A mini road trip, and you like humiliation but not pee. I have just the thing for you
While on that road trip stop at a place that has public toilets. Preferably one that's always busy and has a line of people waiting. Before you enter the store splash some water over the crotch area of your pants/dress, and then slap your cheeks a bit to make them red like you're blushing. Then walk into the store at a fast pace (like you just peed yourself and have trouble holding the rest in) and get in line for the toilets
