When guys discover polygyny, they often treat the decision to take another wife in the same way that they treat the decision to buy a car. They want to know where to go to make their selection.
The reality is that there is no group of ladies hanging out somewhere waiting for men to snap them up. Men are coming to the understanding extremely slowly, and women are even slower at accepting it. There aren’t enough to go around.
I have friends that have searched half a lifetime for another wife and still haven’t found one. Most of the people on this forum are in the looking process. To be frank, an 81 year old guy is at a great disadvantage, as
@Daniel DeLuca kinda hinted to you.
Unless Yah chooses to bless you, your responsibility before Him might simply be to be a supporter of the concept.
