Not your choice, koushi.
I don’t believe monogamy is natural for men, & it does a disservice to women as well.
As we age, more women are available to marry than men due to men naturally taking more & higher level risks. More men are either married, incarcerated or dead, leaving women without a lawful outlet for the sexual urge. Polygamy fills the void.
As for this “Pastor”, if he practices a religion that does teach one man one woman—not mistress, not “baby daddy”— than he is a hypocrite.
