I was just browsing this Tumblr for reference photos and it occurred to me that I ought to share it with you guys. It is a really startlingly tasteful Tumblr dedicated to, well, mostly naked men. But the images are gorgeous and graceful—and sometimes quite poignant—as well as sexy, and are the sort of thing that can be really useful for artists looking for references and models.
Also no lie, these guys are a lot of fun to look at. ^_^
