I have read Earthian because I was brought up in Japan, and some other girls comics which my sister was reading.

They aren't for girls Yaoi things, but I'm always thinking comics of Yosikazu Yasuhiko are very homoerotic. His interest toward men's body makes me regard him as bi. They are for adult. In "My Name is Nero", Roman soldiers rape German gladiator! I have it yet at my sister's house in Japan. Of course his works are excellent.
