My guess would be yes. I think it would be about the confidence the woman has with her body. My wife would have never shown anyone anything, until she had breast augmentation. A year later, I caught my conservative wife sending pics of her tits to a man. She would have never done that if she didn't have the new confidence in her body. So, my assumption is a woman with good body image would have more confidence to share it. I think a lot of wives don't cuckold a willing husband, because they don't think men will find them attractive. Of course, there are many other reasons.
