Very funny.So this man thinks that the woman herself is capable of choosing what gender of a child to bear?As far as i am concerned,a child is a special gift from God regardless of its gender.There is no need to marry a second wife to have a male child because you can not be 100% sure that the second wife will give you a male child.The second wife can even give you twin daughters.What if you dont succeed?How many wives will you marry?
Not monitoring as such, there is no problem in having a look at whats in your partner's phone.If partners are faithful to each other, none of them will have a problem with that unless.However respect is important.
