That's quite common in The Netherlands. Quite a few people emigrated from the Dutch East Indies when the VOC ran things back in the old days. It makes for some interesting scenery in Amsterdam's Red Light district.
That's usually the sign of a bunch of jealous women protecting their 'territory' combined with weak men. See the other part of this thread about hive-based species (matriarchal). They drive out competing females (other hives) and maintain control over their males.
In more advanced societies, the men don't oppress interesting looking females. They just try to date them. ;-)
