I really love rare pairs so feel free to surprise me with a combination of two from my list OR someone from my 'regular' character list below. Have fun mixing it up in some new and exciting way (e.g. Tonks/Stan, Dudley/Pansy, Viktor/Lavender, etc.).
I am also very fond of Molly/Arthur so would prefer you didn't put them in a relationship with anyone else unless there's some way to work around Molly/Arthur and keep it intact (young Molly or Arthur dating other people prior to their marriage would be fine – or even a threesome with M/A and someone else…please don't break them up! *wibbles*)
I really love the following characters: Tonks, Bill Weasley, Charlie Weasley, Luna, Ron, Neville, Ginny, Harry, Fred & George, Sirius Black, Kingsley Shacklebolt, Pansy Parkinson, Lavender Brown, either Patil twin (or both), Angelina Johnson, James Potter, Lily Evans, so inclusion of one (or more) of these would be just grand. I'd also be fine with Draco if Myrtle is involved.
I also love assertive female characters, threesomes, bisexuality, angst, humour, banter, UST, sexual exploration, happy endings, EWE, true love, light bondage/discipline, spanking, seduction, romance, kissing, shower/bath!sex, frottage, and plotty stories over PWP. Exploration of the Wizarding world makes me very happy. So does the use of magic in a sexual setting. I love first times or courtship – I love to know how and why a relationship ticks vs. a schmoopy established relationship with no explanation. I'd love to see a plausible romance between one of the Beholder characters and one of my faves (or more). I love strong characterizations and learning how/why people tick.
I really dislike: any/all Next Gen characters, so please please please avoid them at all costs. I hate Ginny!bashing and Tonks!bashing so if you can't write them nicely, then please don't include them. If you need to break up a relationship, just have it not work out rather than inflicting painful, horrible death or deceit, or just ignore them completely. I also dislike stories with characters who only appear in the books briefly or not at all (i.e. Morag MacDougal or Stephen Cornfoot).
Bestiality (including Animagi forms), Death Eaters, vampires, werewolves (esp Werewolf!Bill), obsession with Muggle pop culture by Wizards (i.e. listening to current bands, reading American comic books or manga, watching 'Star Wars' or whatever), Americanisms, cross-gen relationships (mainly with people of Harry's generation/anyone more than 10 yrs older than them*), piercings, song fic, anachronisms, gender fuck, body/gender swapping and Tonks-with-a-dick are all turn offs too.
* And just to confuse you, I have no problem with the concept of Sirius, James, Bill or Charlie with an older woman so one of them with Minerva, Rosmerta, Hooch or Trelawney would be fantastic should you chose to go there. I'd also be more than fine with Tonks/Moody. Just not anyone in Harry's generation or later.
