Is polygamy a common theme in the culture regions where Czech is spoken? I mean, I can imagine this sentence can have more than one meaning. i.e. -men as in soldiers (they are your soldiers) but could it also mean they are your husbands?
It is not :) Besides soldiers, policemen or firemen it can simply mean male members of a family. You can ask a lady how are her husband and sons this way.
However, it HAS certain teasing potential.
