The only time I have post myself was if I lost a bet and the forfeit involved me being posted but then it usually gets removed when the time is up, that is how my profile photos come to be posted at the moment.
No one has, as far as I know copied and reposted any of my photos, but if they ever did I hope they would tell me. I know I would be embarrassed knowing I was exposed like, but I also think I might find it exciting but not having experienced it I could not really say. I think would accept it in a fun way despite my embarrassment.
If I was ever recognised by someone?,
that would really be an embarrassment overload. I could probably think up some excuse for it but at the end of the day I doubt anyone would believe it and knowing they had seen me naked and probably saved the photos and posted them on further, that would be really embarrassing. It is one of those things that you could never take back or erase, you would just have to live with the fact for the rest of your life and knowing my friends they wouldn't let me ever forget it. But as my exposure has been very limited I doubt it could happen to me.
I have found a friend of mine post topless on a site but it was not posted by her and I have no idea if she consented to it, probably not. I was just a single photo with no information or comments that would make me think she knows about it so I have not said anything to her as I want to spare her the embarrassment and I wouldn't wish to cause trouble for her. I have never reposted it but I have kept it and I do sometimes think to myself when I see her " I know what you look like naked" which is fun.
