Haha. There are. I think most people like to write XXX fanfic cause they want to sort of act out what they think a character would be like in that way or they like to ship characters. I find it funny when they ship characters from Who and Supernatural or Who and Sherlock or Supernatural and Sherlock or all of the above. xD And usually when shipping characters they do male on male, which I don't mind but that has to mean something... Does that mean that most main characters are male or is it cause people like to put two good looking people together and most people are like, "Awe... They'd make a cute couple..."
