So. I recently got the Loudest Whisper and Naughty But Nice mangas from a local comic book store (Lee's Comics in San Mateo). It seems that while most of the local bookstores carry manga, they don't carry yaoi and/or yuri.
Overall, I liked Loudest Whisper better than Naughty But Nice. This is true for the volumes as whole works, and the stories them selves. Both mangas had chapters 1 through 3 of their title series.
At this comic store, I found a fair about of sexually explicit manga, but most of it was over-the-top (bukkake, so-called "->-bleeped-<-" hentai and the like).
Does anyone have any recommendations? I'd recommend Loudest Whisper for yaoi.
