I've been wondering for awhile now, whether this has ever been addressed in any of the books. While I understand that the Gene-Seed is not something that can be passed on to offspring through simple reproduction, and therefore you can't "Breed" new Space Marines, I have yet to find any mention in any of the Novels and/or tabletop Books, that makes mention of whether or not they are Capable, or even interested in Sex. I'm Loathe to try a simple web Search, since I have no desire to be bombarded with conjecture, and the obvious "Fan Art" that such a search would inevitably turn up. I'm simply curious as to whether Games Workshop or their Affiliates have ever addressed this question?
