(not my post, but i don't think the OP is on here, and i think many people here would be excited about it) boyish² is a collection of short yuri comics featuring boyish/butch characters. it's some great representation, you rarely see butch4butch works!!
the first book is great and it sounds like you can still get it! but this second one has a lot of stories i'm excited for and some really great artists onboard.
here's a link to the kickstarter if you want to fund butch media.
