It's the kind of thing that makes porn difficult because there's so much feeling behind it that trying to boil it down to sex feels like cheapening it or something.

To me, it just isn't the kind of relationship that *can* be boiled down to sex. The sex is happening, I think we all agree on that, but because of who they are and how they relate to each other, it's woven into the relationship in a complex and meaningful way that is just extremely difficult for me to get right in my mind.

I don't think that I've ever written a "stereotypically" romantic pairing, so I wouldn't know how to approach writing sex there, either. But usually it's easier to get from desire to actual sex, when here, there's so much else that plays into it... and in the end, the physical desire is the least important part of their all-encompassing desire for each other.
