I love the feeling of my bladder being really full - it turns me on ... if I'm at home I'll play with my **** while trying to hold on ... until it's just too much and I either need to make myself come (which means I can't hold on any longer) or I need to let it out. Usually I make myself come. Sometimes though I like to go for a walk until I can't wait anymore and I find as quiet a place as I can and pee whereever I am. Sometimes that can be a challenge - I've been caught a few times. If it's a guy, mostly they just like to watch, but women can get quite uppity about it.
