Hmm, it's pretty tough to try to categorize what types of yuri I'm addicted to. Well first, I guess you can see that my moniker is Sol. As for types of yuri, I guess I like incest and pseudo-incest, yuri where the participants neatly match and contrast with each other, yuri where both partners are really feminine, yuri based on close relationships from early childhood, and yuri based on long-lasting secret/unrequited love.
Haha, a rather specific list, yet I still don't think it's comprehensive. There's just too much yuri I really enjoy, I probably could never capture all of it.
