!! OMG, he's naked: James Marsden !!
I don't know what it's from but there's a full-frontal pic of James Marsden (Cyclops from X-Men) after the jumpie, so jump!
Ed. Note: Apparently this is Leo Nemeth, not James Marsden in the nudes, but worth a gander nonetheless! Thanks to CB for pointing this out.
