Awww. My fav BL comics is mainly sexual... (˵ ͡° ͜ʖ ͡°˵)
There are also some good comics, which I enjoy and which were mentioned as "BL", but most of them are slowburners. So slow that BL part is not revealed or have only began to reveal in them so far...
This one have mostly light coloured vibe and is cute:
More angst:
More adventures, more content and many well-done characters of the second plan (free to read):
This one is too short so far to say anything specific, but yet is fun:
This one contains BL+GL and action:
About the anime - I'd recommend Ai no Kusabi (I mean OVA from 1992-1994 year; I haven't seen 2012 version so far, so can't say anything about it). It contains sex scenes, but they are not expicit and occur not often. It is tragic anime (I luv tragic anime).
