I'm a little sad to see the chain of comments there where some people are like "We wish there was one with guys instead, or even one that was both" and he's like "Oh don't worry, there's men in here" by which he appears to mean "The True Blood picture has a guy who isn't the focus of the image"
I have the calendar, just showed up last week, and believe me the artwork is gorgeous, everything is tastefully done. And as for having another specific men calendar in the same vein, I don't see why not.
As to male vs. female, I'll buy the female one for myself every time. That's just the way I'm wired. But I'd definitely buy a male one for more than a few friends I can think of off the top of my head.
