Your standards aren't low, just a bit more broad minded than others. And I agree, that guy looks cute.
The picture doesn't look photoshopped to me either but I don't see it as evidence of him being gay. I plant kisses on the cheeks of my straight friends all the time. Well, not all the time. But it never leads to me sucking their cocks.
I actually have extremely broad taste in men, I have no "type" at all, I just happen to think the random guy in that photo is not hot, and that he looks like a goblin. I certainly think that if Andy Roddick were gay he would likely be scoring guys way, way above that guy's weight in terms of attractiveness.
But I'm with you on the possible implications of the picture.
