As someone married to a Russian wife (whom I met through a "mail-order brides" service), I can tell you that the gross generalizations mentioned in the other answers are not true at all! Of course, if you approach this as you "buying" a woman and if you expect your wife to just "be submissive", it won't work out. Plus, you don't "get" a bride from Russia (like in a catalogue...); you meet several women and wait to find the right one. Alas, that is how I proceeded.
I have been married with my wife for 10 years now; I am 55, she is 30. We have two wonderful children, one of whom she had from another relationship before meeting me. I am still madly in love with her, and I believe the opposite is also true.
My wife is anything but "submissive"... She has a heck of a temper, and when she is not happy with something, out of her way! She has an opinion on everything, and most of the time we disagree and argue (it's part of our love life!) For instance, she is a registered member of the GOP, and I'm a convinced Democrat! I'd say the power in the household is split 50-50. And she insisted on getting a job (a hard one, at the minimum wage) even though my revenue was much more than enough for our family to live off very comfortably. She does her part in contributing to our revenue, and for her it is simply a matter of pride.
Since our marriage is based on LOVE, our sex life is PASSIONATE. My wife doesn't ask much of me (though I encourage her to) but eagerly plays along each of my fantasies, some of which my American ex-wife would have divorced me had I just shared them with her. She always brings me with her to buy her clothes and makes me choose those that turn me on, and regularly enquires if there is a way she could change her appearance to please me. ("Baby, I'm going to get my hair cut, what do you want me to do?") In the beginning, I felt bad about that and kept telling her everything was okay and that she did not have to do that; I thought she was doing this only because she thought she had to. One day she got seriously mad at me and said: "Look. I love you. And I do this because I want to. So stop feeling bad and play along!" I do so now, and I feel like the luckiest man on the planet.
So yes, I believe marriage to a Russian woman, IF BASED ON REAL FEELINGS, is a good and viable option. But you should change your approach.
