Polyandry - interesting
Going by the comments that some members make regarding their DH, I can't imagine too many women really wanting more than 1 hubby. 6 kids plus 2 or 3 big kids. Good luck
Assuming two husbands, she could double the laundry, double the cooking and cleaning, double the aggro, double the big boy's toys, double the fun, double the sex (could get a whole 6 minutes rather than the measley 3 minutes)
