My relationship is similar to this, and my Girlfriend definitely WANTS it to be that way. We have trust and respect with each other, and she's smart and can take care of herself, but she LIKES that I take the leadership position in the relationship. She knows I consider her needs and wants when I make a decision, and she's happy to let me make them. Comforted even.
There's nothing wrong with this at all. The important part is to find a guy who truly understands the whole dynamic at work, and that's where you'll have some trouble. You're young, and most younger guys simply don't get this at all. They either don't know how to be a dominant leader, or the only way they know now to be that is to be a jerk to abuses the girl and takes advantage of her. Neither one will work; there MUST be respect and trust, both ways, in this type of relationship, even more than in a normal one. Most guys need some experience to figure that out. Myself, I didn't "get it" until I was in my late 20s.
As you can no doubt see from that website, there are plenty of people who prefer to structure their lives like this, and again, as long as there is trust and respect, there's absolutely nothing wrong with it. There are also households where the woman "wears the pants" and is in charge, and if that's what makes them happy, there's nothing wrong with that either.
The important thing is to know what you really want, and once you know, then you can actually get it. It's hard to get what you want when you don't even know what that is.
