!! OMG, he's naked: Daniel Letterle !!
This one is a bit obscure, but you'll see why I had to post it when you see the screen caps after the jump [NSFW]. Daniel Letterle starred in The Mostly Unfabulous Social Life of Ethan Green, a gay romantic comedy based on the widely-syndicated comic strip by Eric Orner.
In the scene depicted after the jump, Ethan is getting it from this jock guy who makes him wear a football helmet while they have sex. It's hilarious, and sort of hot. You can watch the full NSFW clip here.
