I've experienced two things;
1) you really have to be in the "in" crowd whether in the BORG or just in society in general to get a wife/gf, or just popular
2) secondly, inspite of the more sisters/girls in the BORG over the young men, it was pointed out to me many, many years ago that the sisters/girls actually do the choosing to create the opportunity for the brother/man to ask for relationship or marriage.
