So I find stuff on tumblr quite often, but sometimes I think they're not always worth making a whole topic for or I just feel dumb posting so much.
So! How about we start a topic for tumblr posts? This can include videos, gifts, photos, art, or whatever you find. Male and female both welcome!
Here's a few things I've just found recently:
http://fuckyeahholmescest.tumblr.com/post/45116960003/johnnybooboo-sentiment-with-the-holmes-boys Fanart-- Mycroft watching over a young sick Sherlock
The next 4 links are fanart from the same artist-- Kaciart. I looove this artist. A large chunk of her art is h/c. I would seriously recommend just looking through all her art. It's gold.

http://sherlockspeare.tumblr.com/post/46895721150/brittaniethekid-deareje-new-tab-for-high SUGGESTIVE photo of Benedict. Before you get too excited, you may have to use your imagination. Third photo down. It looks enough like a pre-sneeze face to get me going though...
