These are some general likes/dislikes that are easily applied cross fandom. For a slightly more detailed, HP-specific list, go
here. Inspired by
alby-mangroves. :D
I Love:
General:
AUs, light angst, hurt/comfort, tattoos/piercings/scars, glasses, competence and intelligence, magic or power reveal, possessiveness, creature!fic (werewolves, vampires, etc), humor, banter, forced proximity (arranged marriage, shared bed), reincarnation, awkwardness, pining, cleverness, age disparity, bi/pansexual characters, getting-together fic, UST, bonding!fic (arranged marriage, ~magical~ bonds), plot, PWP, a/b/o, fusions, acknowledging/exploring childhood and it's impact on the characters (Harry's shitty past w/ the Dursleys, Tony Stark's issues with Howard, Thor/Loki's relationship with one another and their father etc.), strong female characters, supportive friendships, explicit sex
Sex related:
Detailed kissing, oral fixation, exhibitionism/voyeurism, DIRTY TALK, masturbation, rimming, sibling incest, secret sexy underwear, sex in public places, loud sex, voice/scent kink, sex outside of the bedroom, sex toys, mutual masturbation, role play, nipple play, multiple orgasms, self-fucking with toys, edging (delayed gratification, drawing it out), being held down, possessiveness and jealousy, frottage, topping from the bottom, shower or bath sex, oral sex of all kinds, exhibitionism, first times, make-up sex, anal sex, dubcon of the made-them-do-it/sex pollen variety, a/b/o, knotting, biting and marking, barebacking, light bondage, blindfolds, D/s dynamics, blowjobs and face-fucking, rough/angry sex, sleep sex, somnophilia, partially clothed sex, power dynamics, I almost always prefer the character in the pairing that is a bit more evil/morally grey/less innocent to be the one who tops or who has a toppier energy
I'm Not a Fan Of:
rape/non-con, major character death (when not canonical), non-con/public humiliation, epithets (the other man, the brunet, the younger man, etc), scat/watersports, dark!characters or dark!fic in general, child abuse, child death or miscarriage, mpreg (in general), baby and kidfic (in general), infidelity (particularly the main pairing cheating on one another), flat-out unhappy endings (ambigous is okay, as long as there's hope!), crossovers, polyamory, rentboy!fic, excessive homophobia, lower-rated fic (generally I like some smut included in my fic)
