So I've been on a bit of a girl!Dean kick lately and am looking for a couple that I lost and a couple general searches of that kind.

1. Teenchester fic with changed-into-a-girl!Dean. Dean and Sam used to be together before Dean got (permanently?) changed into a girl. After the change, Sam is reluctant to hook back up...though not because he doesn't like girls? I think he felt weirder about hooking up with his sister than he did with his brother or something. I remember one part with Dean painting her toenails because she used to like that on girls before she was one so she feels it's only fair that she do it to herself.

2. I'm not sure if this one is real or if I just imagined it. Always-a-girl!Dean is a lesbian, but finds herself falling for Castiel despite his male vessel.

3. Are there any Sam/Jess/Dean fics with girl!Dean? I searched high and low on Delicious, but couldn't find any. I'd prefer always-a-girl!Dean, but will take changed-into-a-girl!Dean because I'm desperate. (Seriously, this fandom has everything. How can this not exist?)

4. Any girl!Dean/Castiel fics that aren't at the Dean/Castiel Epic AU list I love this pairing so much, but I think I've read all that fics that exist for them. :(
