Yaoi and Boys Love are the same thing, shounen-ai is literally “boys love” but it is used to refer to soft yaoi as Gravitation and Loveless. I use the tags “Yaoi” and “Boys Love” in all the pictures to make them easier to find. “Hentai with guys” is including in Yaoi/BL too, that’s why we use the word “shounen-ai” to refer to the anime/manga without sex scenes.
It’s kinda confused, I know. XD
sorry for my english. :~
