I notice many affairs in the workplace involve a married businessman and his young, usually single, female client, coworker, secretary or subordinate. Why can't wives work for their husbands and eliminate their need to spend the entire day with some other woman?

You may have noticed, single men rarely become overseas missionaries, pastors, ministry leaders and such. Married men will do those things, single women will do those things, but not single men. So is it more correct to say that men who have wives make better pastors?
