You know, I think I've become comfortably numb, too--great way to put it! When I first discovered fandom I couldn't get enough of the sex, but now I'm kind of "eh" about it. A lot of times I'll actually skim/skip the sex so as to get on with the good stuff, and I'm much more inclined to fade-to-black in my own writing than I used to be. It's actually a bit sad, I think, as it's become very, very rare that I'm titillated by sex scenes anymore. :-/
