Staring At the Ao3 Page

I really want to write smutty stuff the way I used to - quick, dirty, and no holds barred (heh).

But I haven't been able to do that for a long time now, and no matter what sort of prompts or ideas I get, it's just not happening. At best, I can manage some sort of 'fade to black' moment, and that's it.

I've tried to figure out what the problem is with that, and I think it might go all the way back to my public WIP, The Deal. That story got stuck when I started editing the porny bits, and I never got back it. I started posting it unfinished, because I thought it would help jolt me to write it, but instead I lost all interest for it (in my head it became finished because it was posted.)

And that was two years ago. That story is the last XMFC story I've posted (not counting the remix) so it stares at me every time I go to my AO3 page, and I feel guilty about it every time.
(...Which might be the root of my posting anxiety as well, because I obviously feel bad opening my AO3 page)

Obvious solution is to finish that story and finally get over it, but I have no clue how to do that.
