Xenophilia or Xenophily means an affection for unknown objects human or non-human beings. It is the opposite of Xenophobia or Xenophoby. In common usage it means an attraction to foreign peoples, cultures, or customs.
The word is a synthesis from the Greek "xenos" (ξένος) (stranger, unknown, foreign) and "philos" (φίλος) (love, attraction).
In a more sexual context xenophily is a desire to look for sexual intercourse preferably in unfamiliar situations (e.g. in a church or park) or especially with strange, different, or even absolutely unknown persons.
In common usage it can also mean being sexually attracted to a person distinctly different from oneself, such as in coloring, body type, accent, mannerisms, cultural identity or behavior, etc. To some xenophilia includes even relatively subtle distinctions, but more usually it refers to things of a much more extreme dissimilarity.
Xenophilia is a theme found in science fiction, primarly the space opera sub-genre, in which one explores the consequences of love and sexual intercourse between humans and non-humans, including extraterrestrials. For an unusually light-hearted, satirical, and playful look at this, see XXXenophile, a fully X-rated comic book wriiten by Phil Fogilo.
In the Harry Potter series, Luna Lovegood's father is named Xenophilius Lovegood. He is the editor-in-chief of a magazine called The Quibbler which is comparable to the real life magazine Weekly World News, featuring articles about non-existent creatures considered strange even by magical standards.
