Infertile couples do not invalidate the principle of male-female unions being open to procreation. I'm not saying that all unions must be capable of procreation, I'm saying that in principle the definition of marriage is a procreative union. Individual extreme or special cases do not invalidate the argument.
So why can't one of your exceptions be same-sex marriage?
Because same sex unions in principle are not open to procreation. An infertile marriage remains in principle open to procreation. That is the distinction.
