Same, anon. I'm lucky in the sense that my partner knows that there's a problem in our different levels of sex drive, but I can't tell if he knows how much it actually gets me down. I feel loved in a general though so I feel bad and selfish when I feel so bitter and sad about how little sex we have now.

Have you and your SO spoken about this in terms of finding out what might be at the core of your mismatch? I mean in a way that's open and doesn't immediately fall into one or both of your feeling guilty?
