I'm also male and reread a lot (see my LJ blog for my booklists, even this year I'm at over 2/3 rereads and this year I've read a lot of new-to-me books). Lots of reasons -- 'comfort' books, to refresh memory (on series when a new book comes out and on specific points of which I've been reminded or want to quote), because I miss the characters or stories, because I'm wanting to read a particular type of story, etc.
Oddly, the one book which I both enjoy and seldom reread is Lord of the Rings. That's because I know it so well (I first read it at around age 12 or so, 40 years ago) that I remember it too well and I find that my "pre-memory" of it is too distracting, I now leave it around 10 years between rereading.
(Oh, BTW, I've found your blog from someone else's link which was from someone else -- you are lost in a maze of twisty links, all looking exactly alike -- and got distracted. I finally realised that you probably don't know me and so thought I'd better say hi!)
