I have no issues acknowledging a conventionally attractive guy, I do however seem to have absolutely no notion of what this actually looks like. I know by dint of existing in the 21st century that Brad Pitt, George Clooney etc are considered attractive, but for the life of me I couldn't take that knowledge and apply it to someone else. I can spot an egregiously "unattractive" dude, but there's a very broad spectrum of men that just look like "blokes" to me.
