I know yaoi is fiction but how come no one ever seems to use lube?

Lol true. Tho some manga do show when they use lube, like some parts of kuroneko kareshi (there are a few others i can remember but not the titles). I've noticed most yaoi mangas just use saliva, moisturizers or the uke's natural lubrication (im not even sure if this is a real thing prob not) ╮(￣▽￣)╭

Because in yaoiland, the anus can get wet. (LMAO jk, recent mangas show them using lube though)

Sometimes it's just implied. But if it's no implication then saliva it is. If fantasy or AU yaoi's i just imagine they have powers or something hahahahah

it bothers me, too. I like Elektel Delusion because the issue is handled very well.
