I think people would have a preference, but if it differed from what they usually like, it wouldn't be that big of a deal.
I also think that men and women would still be able to make children, and have those children grow up in a hetero family. But I also think that a lot of accidents would happen and adoption would still be an option for those that will grow up in literally any sort of family at all. So offspring wouldn't be that big of an issue.
