Pairings (in alphabetical order): Barty Crouch Jr/Aurora Sinistra, Cedric Diggory/Harry Potter, Evan Rosier Jr/Alecto Carrow, Fred Weasley/Angelina Johnson/George Weasley (as a permanent threesome/relationship) James Potter II/Lily Potter II (I'm so going to get flak for that one.) Luna Lovegood/Katie Bell, Neville Longbottom/Lavender Brown, Pansy Parkinson/Daphne Greengrass, Regulus Black/Rastaban Lestrange, Remus Lupin/Dorcas Meadowes, Rodolphus/Bellatrix Lestrange, Scorpius Malfoy/Lily Potter II, Seamus Finnigan/Ginny Weasley, Teddy Lupin/Lily Potter II, and Viktor Krum/Hermione Granger.
Things I Like:
Plot, reincarnation themes, dark fic, hurt/comfort if it fits the pairing, kink, erotic asphyxiation, bondage, D/s as long as it's a almost romantic D/s situation (even if the sub is technically a slave), bloodplay, cross-dressing (especially women in drag), dominant females, dub-con, whippings if not severe, seduction scenes, romance, sex in awkward places, sex where you might get caught, bruises left over from amorous encounters, fidelity, lots of foreplay, oral, rushing to get undressed, desperate sex, fighting or contests to be on top, formal clothing, corsets, gowns, roleplaying, muggle-to-wizard confusion or vice versa.
I'm not really squickable, so instead this is a list of things that I don't find hot or turn offs:
Scat, vomit, urine, vore, dildos in girlslash, and necrophilia.
