Is there a way to put the ball in her court and have her list the activities she is willing to engage in with some frequency and a list she is not? Then maybe you would get more frequency if you promised to make no more photography requests if she is never going to be comfortable enough with her body for that. I'm just pointing out that many women would be too uncomfortable with their bodies to regularly engage in that, but the same women might be open to other things. Just an idea. Sounds like you are in a very resentful space right now because these discussions have been going on so many years.
