Ermm I like to read about MCR/The Killjoys, FOB, P!ATD, Batman, X-Men, Deadpool, The Gorillaz, Tokio Hotel, Black Butler/Kuroshitsuji, Naruto. Ouran High School Host Club,  Sherlock, Doctor Who (preferably 10th or 11th Doctor), Randy Orton, Matt Hardy, Triple H, Batista, CM Punk, Kane, Undertaker, Jon Moxley/Dean Ambrose, Dr. House, Spencer Reid, or Sheldon Cooper.
Harry Potter! But only with Draco Malfoy or Severus Snape. 

Maybe Tome Riddle/He Who Must Not be Named Tyler Black/Seth Rollins, Husky Harris/Bray Wyatt, Wade Barrett, Edge,   Escape the Fate, or Falling in Reverse fic once in a blue moon. Sadly almost no Top Gear fanfics have been invented.
***Obviously extremely random thins I have found myself reading at some point in time.

I read (male)/OC fics, I can't stomach twincest stories like Mikey/Gerard or Tom/Bill, StudentXTeacher stories like SnapeXHermione etc. It is probably obvious I prefer reading character stories that stay true to cannon rather than the twisted fannon that some people created.

Examples of "twisted" fannon: CM Punk that isn't straight edge, a pescetarian, or a grammar nazi. Jeff Hardy never having an addiction issue (unless it was written as a story before his addiction problem). Fannon that has Jon Good aka Ambrose/Moxley as a sick and crazy guy (read interviews about him he is actually a really chill guy), same thing with Glenn Jacobs his persona is the opposite of him IRL. Bill and Tom not being vegetarians, Bill wearing leather (it is fanfiction. IRL Bill would wear only faux leather if possible as opposed to real leather, so that animals weren't harmed), Andy Hurley not being written as a straight edge vegan, Pete Wentz has Bipolar Disorder and IS a vegetarian(, Sheldon Cooper not being a germaphobe. Just standard stuff that you could easily Google and should if you want a realistic character unless written before info came out.

 P.s. I'm not a homophobe I just prefer to read about things I know.
