As I understand it, that is common when the wife is shared. She is free to do whomever she pleases, but the husband must remain faithful. I had one experienced shared wife tell me that if her husband had sex with another woman, she would be terribly hurt, and it would be grounds for divorce. Fortunately, most husbands who share their wives have no interest in other women and are content with their role. A double standard? You bet it is, but most of the couples are happy with this arrangement.
