They have sex! That's basically an automatic classification as Yuri. Seriously. Seeing as how Yuri is defined on this website, I think it would be obvious that that would be the case.

Your point?
Just add it to the genre list.

Hrodulf and Bjornolfr, you will not be forgotten.

If I had a fantasy self, it'd be a tentacle monster.

It doesn't show them having sex though, so I wouldn't really count it

Actually, I don't quite see the point of two separate "lesbian" genres at all.

Shoujo-ai is supposedly the base genre for lesbian romance, subtext, and annoyingly often even just for side characters with (minor) lesbian tendencies.
Yuri is shoujo-ai topped with the occasional nudity and sex scenes.
Smut is the middelground between conservative/pure romance and full blown hentai.
Hentai is pure sex (18+ manga)
Ecchi for fanservice

... Why not simply combine smut and shoujo-ai instead of using yuri... Or simply get rid of shoujo-ai and replace it with Yuri altogether... Now MU kind of insinuates that Yuri means lesbian sex (which it does not).
And we now have to contend with 4 separate genres to indicate homosexual manga... Where 2 would suffice (and be better in my opinion), when having already indicated a manga deals with lesbian pairings, isn't a simple tag called "smut" enough?. I most certainly won't be confused by it... If you'd like to indicated a manga contains lesbian+gay pairing and gay sex only, that would be something for the "tags" (or categories), NOT genres.

So to respond at the topic title. YES, it's definitely Yuri. All manga containing Lesbian (romance) are.
Shoujo-ai is often the incorrect term, since it insinuates that it's love between (young) girls... Which kind of makes it also lolicon?

Anyway, /rant

Lets just call it all manga.

I agree with this. The way MU defines it, I'd say 'yuri' is when there's actual graphic sex depicted in the story, not when they mention it in ing/discuss it or cut-to-black and/or fadeout the 'scenes'. The one would-be-explicit shot in Candy was faded out, so it's not yuri.

As far as I'm aware, the way the English-speaking manga fandom categorizes BL and GL is different from how it's done in Japan. Tagging for BL manga follows the "yaoi for graphic sex, shounen-ai for no sex or merely implied sex", so I don't see why it shouldn't be applicable to GL.
