Not really, romances have been a part of RPGs, at least Western RPGs(haven't played a lot of JRGPs) for a some time now and it doesn't look like it's anywhere. It's nice to have the option to do it and a lot of times it's a way of getting to know that person really well, since a lot of the characters open up more, once you romance them and make them "vulnerable". I do it for that reason, the whole sex part, especially in Dragon Age felt stiff and awkward and whenever I choose to romance someone, when I play it, I just skip over that part and move on to the conversation.
Also, as a note, you don't *have* it's an option, not a requirement. I haven't played any RPG, where you're forced to romance someone. It's like a side-quest that doesn't give any extra xp, but adds something to the character.
