My boyfriend reads also, though not quite as much as I do, and not the same kinds of books. He tends to read graphic novels/manga and technical books, though occasionally I'll convince him to dive into a literary work and he'll love it. Otherwise, he is prone to starting a book and finishing it 7 months later. We have a lot of bookmarks at his disposal.
He doesn't find it weird that I read so much, but then again, he spends equal amounts of time playing video/computer games, so I doubt he even notices how many books I finish.
