Porn, romance, erotica, smut, etc. – how do you define and distinguish them?
I'm a descriptivist rather than a prescriptivist. I don't think there's a coherent description I can use for pornography in prose. I've heard some describe it as fiction that hops straight into bed (I'm being a bit less crass here than what I've actually heard). However, if that's the definition, I've literally never read written pornography.
If you were to apply the same standard to video, you'd only be able to consider things porn when they've been trimmed to not show any of the setup. Considering the way that many people view porn is unauthorized clips on video sites, that wouldn't be surprising but it's not how those videos were intended to be watched either.
I think a reasonable definition of romance is the story of how a romantic relationship begins and eventually establishes a form of stability. It can either have explicit sexual content or not while still being romance. For erotica, I think a significant focus on sexually arousing material is probably where I'd go with that. Romance can be erotica and erotica can be romance but they're not always compatible with each other.
I feel like smut broadly means that there is steamy, sensual material in a work. It can encompass work with no actual sexual content in it as long as it's approaching that. It doesn't need to be erotic or romantic in order to be smutty. Though I don't really find that much fun myself.
Does it matter?
If this was some other genre convention, I'd argue that this was a question of whether or not we're keeping the genre contact with the reader. Unfortunately, I don't think there's enough concensus on these terms to do that. As long as we are accurate when we describe open-door vs. closed-door (for Romance) and similar specifics, I think we're probably doing as best we can.
