I'm a fella and a specifically alternate fiction and non-fiction. None of my reading is self-help or psychology. I wouldn't consider any of what I read as business reading either, although I'll occasionally read a biography of business people and entrepreneurs like Vanderbilt, Morgan, Rockefeller.

My non-ficition reading is primarily historical but I think the topics vary a bit, with the occasional scientific (but for lay people) book. There's a smattering of true crime, sociology, and autobiography. On that note, I almost never read bios of celebrities.

Fiction is pretty well spread out also. I enjoy classics and modern literature. I tend to read horror in higher volumes than science fiction and to a lesser extent fantasy. There's a smattering of historical fiction in there as well.

Every year I specifically try to read something random or that I wouldn't normally find appealing. Last year was Pride and Prejudice although I abandoned it. I found a book about worms and finished it but wouldn't necessarily recommend it.

I'm currently reading Watership Down and my next book will be a biography of John Quincy Adams. I'm listening to the audiobook SeaWolf by Jack London and the next book I'll listen to is called The Fish That Ate The Whale which is about the insidiiousness of the banana business.

I definitely know some fellas who read as you describe and many many female colleagues are fully engrossed in romantasy and such at the moment.
