I don't like them over muscled.
I don't like twinks--I don't want to feel like a creepy old woman when my screen saver comes on.
I don't like the coy cover up. There are so many photos with an awkwardly held/draped towel or with the guys clutching their stuff. I saw many, many photos with guys either touching or peeking at their junk.
And I don't like the photos where they are pulling their underwear down or showing tuft. And there are some photos that just don't make any sense. Why would you wear underwear in the shower anyway?
Guys and girls are definitely different, even guys that like guys. Oh, and no matter how much I like milk, this is just gross:
What I do like is a nice, artsy, sexy photo.
