No real preference. I grew up in the days of dressing for and showering after gym. Did a stint in the Army back when basic training seemed designed to strip away your sense of modesty and privacy. As long as I don’t have to helicopter my Wang and make slurping noises at whomever is chosen, it genuinely doesn’t matter.
Yup, irrelevant for me, too. Is the person I choose obligated to watch, or are they free to close their eyes, look away, or whatever? I don’t see why I should have any objection to my naked body being seen by anyone who wants to see it.
I’ve spent more time than the average person in nudist resorts and other places where being publically nekkid is accepted. Many people I know have seen me in my birthday suit and I wouldn’t care if strangers did. So add me to the “don’t really care” camp.
I picked “friends.”
What if he forces me to be emotionally naked?
“I…haven’t really lived my life. So many fears, so many regrets!”
The “forced” really removes the edge from this. Maybe something like “who would you be most willing to let see you naked a random billionaire offered you $$$ to do so?”
Hey, that 15 bucks will let me see a movie!
Certain of my relatives have already seen me naked. (Nude beach.)
Why make a stranger or co-worker suffer? There’s enough sorrow in this world.
I sold my modesty for beer money years ago so the big answer, is don’t care.
But out of consideration for female relatives who would be obligated to view the awesome that is me, and would potentially have to spend time in my company in the future, I’ll go with stranger.
Ill naked for all of them will he’ll let more of us go.
It would let me add “Professional stripper” to the old resume, so cash would really get my cooperation. 
I chose friend also but, as a few others have said, I don’t really care. I am not a nudist or anything, but it would not be a big deal for me if people see me naked.
The only group I may have second thoughts about is coworkers, only because I have no patience for nonsense at work.
We get unusually hung up about nudity. As much as I am self conscious about my body and have no great interest in showing it to anybody (I’m not a naturist), I will do so in a sexy situation, a changing room situation, and a medical situation, all without much hesitation. I accept that those are people and events where it’s just what I have to do, so I get on with it.
So in this scenario, I don’t have any preference. I’d pick the most attractive one just so I get something out of it*.
That kind of seems backwards, but I’d rather an attractive person see me naked, even though ideally I’d much prefer seeing the attractive person themselves be naked. It’s a CFNM* thing, I guess.
**A porn category, NSFW
Having only 5 minutes to drink in my naked form is the true cruelty of this scenario.
Another vote for “doesn’t matter.” As long as whoever it was could not touch or assault me, and if they promised not to laugh…
I was a nude artists model back in my college days, and I’ve done way too much low-budget theatre to have any body modesty left. Heck, I’ve been surprised at the few theaters I’ve worked at that had separate dressing rooms for men and women!
This question makes me more curious about the OP than other people’s answers at this point.
I’ll strip in front of all of them and do a ballet if that means I’m no longer kidnapped. I mean, really? That’s such an awful scenario someone might choose to remain dressed and captured?
Keep in mind, SeaDragon Tattoo, there are people who would strip and do a ballet if it meant they were kidnapped longer.
Another vote for any and all, not a flasher but in a flash they will see my flesh.
I suspect the op overcompensated:he didn’t want people to fight the hypothetical, so he made it impossible to say no. Which then made it kinda meaningless to whom you said yes.
I have a rather bizarre imagination, that’s all. That’s by no means the strangest scenario I’ve come up with.
That was part of it. An alarmingly high percentage of people on this board have a hobby of fighting the hypothetical.
So what you are interested in is who people are more uncomfortable being naked in front of?
Well early on after moving to my town I had joined a gym and had no discomfort being naked in the locker room in front o f strangers. Undressing in front of a friend I went to the gym with, slightly less comfortable but okay. Running into my new Rabbi standing naked in front me and being naked myself … that was little uncomfortable. Does that inform at all?
