Not 4? Because, for any Christian, the default answer should ALWAYS be 4. It is only through giving up our own plans and seeking His for our lives, that our lives can have true purpose. So my first advice for you is to seriously consider what it means to serve Jesus as Lord and Master of your life. Because He calls us to leave everything, and follow Him - to find His plans for our lives, not seek our own.
But while your goal is 2, then you need to forget about talking to women about polygamy. You need to learn about talking to women, and getting one woman. Because you have just told me that you would be satisfied with one wife - you'd like two or more, but one would be enough. And today, you have no wives. So you need to focus on finding one wife. You can forget about polygamy for now, it is a matter for the future.
Matthew 6:24
Therefore do not worry about tomorrow, for tomorrow will worry about its own things. Sufficient for the day is its own trouble.
