I've been fully naked in a locked stall twice now. The thrill of that is amazing, the second time I was dared to edge while naked and send a pic as proof.

More than once I've changed in a cubicle, but one time specifically that I remember getting fully naked in one I was changing at the beach, and I was sharing the cubicle with my then boyfriend.

Oh very fun, good thing he didn't steal your clothes

That would have been fun, maybe if it had been night he would've suggested that

Ah, well maybe next time

I've been nude a couple times, not always on purpose lol.

One time I was in a train station bathroom where the doors open automatically when someone calls to have them unlocked and I stupidly forgot to lock mine so it swung open and I had to run over bottomless to try and force it back closed which is really difficult since it's auto opened. I guess you could say I was... caught with my pants down! I was on the other end of that once and saw a random woman's vagina. Woops.

Another time I was feeling horny and daring and stripped off to use a urinal naked. I've done it a few times but nothing really interesting ever happens that I can remember.

I have also, while in a swimming pool locker room, trecked over to the toilets butt naked and used the urinal but nobody really cares. Regardless, love all the guys who see me naked when I do that.

I have stripped down in public restrooms quite often, for dares and for other reasons. Locker rooms or beach areas are not a big deal because you have expect to see someone naked while they are changing clothes or what have you. Truck stops, rest areas, and stores, however, do not have that expectation, so when I walk out of a stall naked to wash my hands or what have you, I get more than a few odd looks... and a thrill from "safe" exposure.

Oh well at least people who have seen are cool about it

Ha ha I'd say you do and I'm not so sure how safe that is

yeah I did it for a dare. I had to go into a stall, take my clothes off and then go stand in the open and send pictures as proof. i was only out for 30 seconds and luckily noone came in but it was still really fun

Very exciting, where was the toilet?

A Big Yes!
 

I'd said that was very nerve racking alright

I have, though it was not really a dare. Well, basically it was. It was part of a webtease and the task was to go to a cafe, buy a coffee to go, find a public toilet, get in, get naked, masturbate and cum in the coffee and finally drink it. It was a cubicle and luckily for me there weren't that many people there at the time.

Being nude was not a part of it originally but I added that bit to it myself. Otherwise I completed the task but at the time (years ago) I couldn't bring myself to drink the coffee after I came in it.

it was at my sports club
