I was a scared prude most my life. Then my abusive gf in college one day decided to pull my loose pants (and subsequently underwear) down in front of about 15 of her friends at a party (trying to embarrass me was one way she tried to abuse me). I wasn't going to let her "win" so I took the off around my feet and took my shirt off and stayed naked. People saw her pull my pants down, and they were happy for me that I wasn't going to let it ruin me. This was before cell phones, so no one took pictures, but people looked, and some women (and one man) followed me around closely for awhile.
I then went into the bedroom after a few minutes, still naked, and laid on the bed, thinking about how comfortable I was naked even though it was completely rude and mean and awful that she did that to me. Three women came into the bedroom after me and we just had normal conversation for about 20 minutes. One of them said, "Let's get naked, too!" and just as one of them had her shirt off but her bra on, my then-gf walked in and got really mad at them. It was pretty dramatic and the party basically broke up and everyone went somewhere else.
My gf was soooooo mad at me that I wasn't upset for her exposing me. She actually helped me break out of my shell in so many ways. (And well beyond being comfortable naked. I suddenly was able to talk in front of people, introduce myself to strangers, perform without freaking out, etc.)
But, back to being naked, I pretty much spent the rest of my senior year in college naked at her apartment in front of her roommates every evening. The other women eventually let me see them in their bras and underwear while getting dressed, etc, all casual, but nothing more than that happened.
But, back to the OP, I would LOVE to be exposed like that in front of a crowd.
