No they dont but i dont really like all femal casts, yuri or not. Nor do i like all male casts lol. Yuri animes bug me because they like to show aslong as your another woman you can do w.e perverted stuff and not be looked down at and labled a sicko.
Its all pure male fantasy and not even made for girla haha.
You mean avy, right? Males have appeared in the first two episodes but aren't part of the main cast. That consists of all girls. I don't see the issue with that though, I don't think you need a male lead in all animes.
