I've never gotten the position that this has nothing to do with the story so it's not in there (unlike every random het romance) when the whole point of it really does seem to be to explain his flirtation with the dark. This "love story" actually is part of the plot...or at least is related to stuff in there. Why would so much of DH be focused on GG/DD without that coming out? Meanwhile the Grey Lady can't talk for two minutes without explaining her tragic love story? Yeah, don't get taht.

It's also sort of funny when you think...the thing is, you can't really become a-sexual, can you? That is, if he's naturally got this sex drive and loves men, what you mean is that he's repressing it or just not acting on it. Which doesn't really sound like a good thing. Unless you see it as something like alcoholism!
