Hee.I knew Zaou Taishi wrote pretty awesome girl love and she co-wrote most of it with EikiEiki, but I didn't know about Minekura - I'll have to look that up.
I knew that GL wasn't a genre specifically aimed towards men in the Japanese market, unlike a western one, especially since most Japanese men were not interested in it at all; but I didn't know it was specifically aimed towards women like BL.
However, there is lesbianism in /anime/ at least for a male audience. Bakuretsu Tenshi - I don't know about the second season, but in the first, it started off as one male character lots of female ones. Oh goodie a harem series! I am going to /kill/ whoever suggested this for the weekly anime screening. And then they decided the male character was boring, so lots of girl on girl action. o.o; (Although two of the girls in question are called Joe and Marco - they were definitely female though.)
There seems to be a lot of the background lesbian characters in what are clearly male orientated series - Mai hime, Mai otame - are shounen series, and mai hime started off as het like, and then brought out the GL couples, and mai otame seemed to decide that the male characters from the previous show were boring - because it wasn't hetrosexual at all. Aha, and that was definitely a male fan service series. SERIOUSLY who keeps suggesting this stuff to screen?
There are also background not really in the spotlight but there there and it's part of their motivation characters, like in Code Geass, another male orientated series...
And there are lots of other examples that I can't recall on the spot right now.
Male orientated Lesbian action in anime tends to portray lesbians as psychopathic though.
