Why do we tie those to sexual relationship status, though? I understand that this kind of thinking has fallen out of favor but the answer to your question is this, because the primary purpose of marriage is for having and raising children. Of course, people who will never have children can and do get married. Of course, people who are too old to have children can get married. And now, people for whom it's biologically impossible to reproduce can get married. Maybe it's time for a whole series of discussions about our society's future plans for marriage.
