I started reading yaoi (like Junjou Romantica) when I was about 12 I think. At the beginning I even turned all red (I once looked in the mirror afterwards), good thing that doesn't happen anymore. I don't remember having a problem with nudity, I think for me it was rather something interesting when I was younger XD
The remake of Ai no Kusabi (yaoi warning!) has quite the pretty art for sci-fi things.


But No.6

And Uraboku are also very pretty.

Though I often like the art in anime, even the huge hands in Junjou Romantica XD
