Single and Married thoughts on Man Caves in the home.

My first reaction seeing a man cave, "Sweet room!" Until.... I find out that it is indeed an actual cave to which a wife has forced all of her husband's passions and interests to be pushed into what is most usually the smallest room in the house. I'm a family guy, so l get sacrificing for the wife and kids, but something about man caves has always seemed...degrading to me. That may not even be the right word, but it makes me feel like, "Has my life really came to this?" I'm at the age where I want one, but also don't want to feel like a dog excited for its tiny house in the backyard. Am I alone in this? I'd like everyone's thoughts on man caves and where you draw the line in terms of what goes into the rest of the house. I feel like there's no right answer, so l am curious how everyone else has worked this out.
