These are under extreme circumstances typically, but say for example you are a 6 foot tall girl. You know the pains of being 6 foot tall as a woman but you want to marry a guy taller. If you have another girl then she will have the same struggles. Or another one is say you are attracted to bigger heavy set men with large shoulders. Do you consider the possibilities of having a heavy set woman with masculine shoulders think of the possible struggles she would have? I am using these examples as typically these are dimorphic traits preferred by women, but on the flipside could create more masculine daughters.
