The reason I like the idea of keeping it as a separate subtrope would be to have a direct opposite to Hormone-Addled Teenager. I think there's some value to that.
Though upon further thought, I suppose a perfect opposite would be more along the lines of a singular chaste teen. Is there a trope for... well, for a prude?
In kids shows, this sounds like an Enforced Trope that would really be People Sit on Chairs.
The reason that it is currently anime only is that many shows have an Improbably Female Cast and not meant to sexualize its characters, something not many Western shows aimed at adults are. Though that doesn't explain the exclusion of video games. To expand to other media would make the trope lose meaning. That's why I suggested that the trope be redefined to deal with shows with Improbably Female Cast not getting involved in romance.
In modern Western Media, there seems to be little distinction anymore. Sad, really.
Maybe because, aside from the shows that I just referenced, there are very few shows with an Improbably Female Cast in the West. (EDIT: And I just remembered that the latter of those two at least has quite a few guys too.) Whereas the Improbably Male Cast was so ubiquitous once upon a time, that its aversionwasTropable.

I voted this up. No one has yet explained why there should be a teens-only subtrope of No Hugging, No Kissing. Sure, you might expect romance between teens, but you might equally well expect romance with any example in No Hugging, No Kissing - if you have no special reason to expect it, it's not an example.
Like I said, every single example of No Hugging, No Kissing is "You'd think there'd be sex and romance here, but there isn't." If the characters aren't the sort of people you'd expect to be romance hungry - children, the elderly, whatever - it's not an example.
