You obviously don't understand how awesome having a man cave really is....and you might be a cuck.
No dude, you misunderstand me. I'm fully aware of how enjoyable it is to have a home that's tailored to one's own tastes:
I just find the term "man cave" to be a bit pathetic. A man cave smells of feet and stale pizza and desperation.
If you feel the need to separate your shared home into your rooms and theirs, you might be an underdeveloped teenager.
