Nonsense. If a man is going to pursue this life then he should start his family with someone who also wants this life. That way they are equally yoked.
Also, planning for another wife is a good thing even if it doesn't happen.
Why? Because the men who make this work the best know that success means:
- They need to have God in their life, in their heart, and at the center of their family.
- They need to be debt free.
- They need to be self-employed so they don't get fired for being poly.
- They need a house big enough for the family they want.
Even if you never add another wife to your family then the family you have will be forever grateful for what you've provided. You will be a role model to your children and you will be a natural leader in your family.
More nonsense.
God made men to have desires and male desire is a gift from God. So long as it is used for Godly reasons then there's nothing wrong with a man seeing another woman he wants to fill with his children.
