Yep, Id have been pretty mad, I think when couples take naked photos of eachother thay are generally both consenting, rather than one of them creeping up on the other when she's not expecting it.
And I don't really understand your defence of, 'she has had loads of lovers before I married her and can't say she has led a moral life'. What's that got to do with anything? So if you've enjoyed an active and varied sex life in the past you have no right to be angry if someone feels like taking a naked picture of you without asking? It's one of the most ridiculous things I've ever heard.
However, if my husband did this, I may have been annoyed, pretty much for the reasons wigglebum has said, but I wouldn't accuse him of being a weirdo, Are you sure she is your wife and you're not just living in a fantasy world where you believe that some poor woman is your wife? Perhaps that's why she was angry, perhaps the whole relationship is all in youe head and you really are a weirdo!
