A while back, at least 10 years ago, there was a bill in the NH legislature against same-sex marriage, and the argumentation in the bill said outright that the purpose of marriage was to breed new taxpayers, so infertile marriages were contrary to proper marriage. The bill went nowhere. It didn't say anything about infertile opposite-sex marriages.
I don't know whether that's a widespread motive for opposition to same-sex marriage, but I don't think so. With most opponents, I think the basic motive is that they're convinced that homosexuality is evil, and legalizing same-sex marriage legitimizes it. Yet there's much more talk about "defense of marriage" than about the evil of leading people down the slippery slope of sodomy. I really don't understand why that is, since the latter argument would seem to be more effective if anything.
