I’m talking about a photo that was taken of you after the age of 18. Baby photos aren’t counted here.
Given that our local space time fabric seems to still be intact I’m going to go with a fairly sure NO.
Nope.
Yeah. I posed nude for a photographer friend when I was 18. In my mid-30s, I was in a sexually overheated relationship and we took pictures of ourselves. We had a charcoal of the two of us nude together done, as well. I have copies of none of these things. The sex pics were really, really hot as we were a remarkably good looking couple… She took them when she left. I hope she didn’t destroy them.
Not that could be readily identifiable as me. Allegedly.
Yes. Polaroids no less, of my wife and I, taken many years ago. Some fairly naughty, some just naked pics.
Assuming that the polaroids haven’t disintegrated with age, of course. After we (hopefully) die of extreme old age maybe the kid will find 'em going through our effects, and be seriously squigged out. 
Nope, probably because when I was young enough to be stupid enough to take or allow such a photograph, you had to take film to the chemist shop to get it developed. By the time digital cameras came along, I had grown a brain (and realised that nobody deserves to see that shit).
I don’t… think so. But I did spend a lot of my college days on the nude Black’s Beach below UCSD in La Jolla. So, wow, it’s dawning on me–probably.
Interesting side bit: There used to be a guy there on the beach a lot who would offer to paint birds and whatnot on your chest and then take pictures. (Give me a break, I was 19 and from Appalachia.) I know I was partly covered at the time, but I do remember noticing that his super-power lens camera was pointed a good torso length below the chest painting. I ended the “session” then. But I have often thought, in light of news in recent years, that he was Rodney Alcala. Seriously.
Maybe. An ex has or has one but I don’t know if she kept it. That was a good 15 or so years ago.
On my phone. Me and my at the time FWB were being naughty.
Then I of course lost my damn phone afterwords. Thankfully, my FWB wasn’t at all concerned when I told her about it. And I can’t imagine why anyone would want to download pictures of me on the Internets. So I’m not too worried either.
I guess that’s one perk for being middle aged with a beer gut.
Polaroid instant film fit the bill for us young and stupid pre-digital camera folks, who didn’t want nudies (or worse) to be seen by the prying eyes of a developer. 
Those were around, for sure, but they always seemed like an expensive luxury (I’m not sure they really were all that expensive, but it seemed like a lot of money for not much photo)
No. You are welcome.
A few, from when I was doing a bit of long distance dating/flirting online a few years ago. I was always careful, though, and made sure my head was never in the pics. So unless you know me intimately, you wouldn’t be able to identify me from them.
I was always careful to strip the EXIF data from any pictures, too - something that surprisingly few people know about.
It was taken, I did not have a choice, I don’t know what has come of it, I don’t suspect much if they even still exist.
Other such picts are plausible, not for me so much, but for her which would have included me by default (by a different her then above).
Maybe. When I was young and stupid and fresh out the Army an ex girlfriend and I took some naughty photos. She may still have them.
Yes, a few from back when we went skinny dipping and no one cared.
Nope. I kind of live by the philosophy of “Don’t do things you might regret later.”
How about nude pics I took of myself when I was 17 and posted online? Definitely not a baby photo (I had a hard-on in one which technically makes it child pornography).
There is one of me where I am recognizable on a nude beach in Slovenia. Nothing is showing, though. And I have the negs (or at least I was in possession of the negs. No idea if I still have them, or not.)
