Yeah ... creepy to you, I guess? I mean, as my post shows, I don't agree with most of the OP's actual conclusions, but the thought of Astartes having sex, or even raping people, doesn't upset me more than the thought of Astartes being child traffickers. 40K isn't primarily a game I play with toy soldiers. To me, it's primarily a story setting, and I don't think about it any less seriously than I think about any other story setting. I can't imagine I'm the only one for whom that's true.
