Berenia, to answer your questions: The answers to all of these is "Yes" with the possible exception of the last one. Still, any woman who will pose naked for photos has, in my opinion, a secret desire to show her naked body to other men. So, when she strips and spreads for the camera, she is really saying "Show my pussy to other men! I want them to look and wish they could fuck me!"
As for the other questions, it has to be the highest of highs for some husbands to see other men staring at their wives' nude photos and saying "Boy, would I love to fuck that!"
That's what sharing of wives' naked photos is all about.
