I haven't seen anyone say this yet...
Would anyone actually WANT 2 wives, or 2 concubines? I Love my spouse with all my heart, but there is no way I could physically or mentally balance two women.
And that's not to say 1 negative thing about women. Simply that I could not handle 2 different personalities, sex drives, needs, wants, reproduction desires, styles, tastes, life views, personal hygiene, favorite tv shows, expectations for social gatherings (parties, friends over), types of friends, personal things they don't like about me, etc. etc. etc.
One is a blessing and one is plenty
