I am now up to about 20 emails/posts/comments a week requesting recommendations for other Yuri titles that people would like me to guess that they would want to read (usually scanlations, because very very rarely do people ask what they can buy.)
I do not do recommendations.
I’m not really comfortable suggesting series for people, because I don’t really know if your taste and mine coincide. And even if they do, I’m still not comfortable making series suggestions.
I will suggest that you join the Yuricon Mailing List and ask there, since a lot of people do not have the same issues suggesting things to other people that I do.
Also, I suggest going to Lililicious, I believe they have their scanlations arranged in different ways and you may be able to find series you like there.
Of course the “Yuri Manga” category at Okazu has hundreds of Yuri manga reviews, but you’ll need to decide for yourself what you are looking for in a manga.
And if you are looking for something to buy, of course I recommend visiting the Yuricon Shop where you will find hundreds of Yuri Anime and Manga to choose from, with synopses and reviews to help you choose.
In any case, I wish you the very best of luck with your quest!
