IS IT ONLY ME??!

After reading Yaoi/BL mangas for quite some years, I find it a LOT annoying nowadays when I read a manga were the seme is experienced in sex even when he is in his early teens and the uke remains a virgin even if he's past 30-40. Why can't the both of them be experienced or let the uke be the experienced one or better yet make them both virgins(which I prefer more). Idk nowadays I just drop most mangas when an experienced seme and virgin uke pops up but keep on reading only if the story is good. Most of the time, there is no fresh story; a boy meets another boy, sex(with a bare consent) in the first or second meet, they are both in love(?), pretty much the same scenario with different characters and settings.
