Yeah I've done screenshots as well but don't and have not ever posted them online. They are in a secure encrypted file so can't be accessed by anyone but me. I love Truecrypt. It's one great free program. Makes encrypted volumes, hidden volumes and even operating systems. Great for keeping private stuff private. (no I don't work for them lol)
Me and my girlfriend's files are in a rar with a password that would currently take over a million days to crack. (It's a picture I drew with the keyboard keys) But it also takes like an hour to unrar and I have way too many old screenshots for that. Maybe I should look into this encryption. Glad I didn't dissuade you from doing what you're doing - but surely you must recognize that some people aren't willing to take the risk of being screenshot, or would not if they knew about the fairly common practice.
You mentioned other men seeing you naked! One of the safest forms of wife-sharing is when a man takes his wife to a nudist club and the other men can look at her naked body at length, and entertain their own lustful thoughts. I have been married three times and I was able to get each of them naked before other men at some time during our marriages. I still have friends who will quietly come around and ask me if I "still let other guys look at my wife's pussy". And I have several good friends who remember exactly what my wife looks like without her clothes. All this excites me and makes me want to fuck her even more. When I fuck her, I remember all those other guys who have looked at her tits and pussy and I cum with a bang!!
I think it sounds like he's trying to respect the fact that you aren't into it by saying he doesn't want it anymore. Or maybe once he knew how you felt about it, it didn't make him excited anymore bc he doesn't really want to make you feel dirty and cheap.
frist you need to have a serious talk about this. if you boyfriend wants you to perform on a webcam or live infront of other men then let that be your choice. in other words would you like that sort of attention. would you enjoy wiggling your booty in front of other guys while they get off on it. when it really come to sex it really all down to the woman. I have been married for 9 years and me and my wife have had sex with other people before in our marriage we just ask each other " hey would it be ok with you if I were with this person you can watch if you want" sometimes yes sometimes no. sex is such a taboo thing with people sense it's filled with raw human emotions. hope my advice helps good luck and be open minded sex can be a very releasing thing depending on how far your will to push it.
