exophilia

Exophilia is an attraction, generally sexual in nature, to new, strange, or otherworldly things, such as extraterrestrial lifeforms, supernatural beings, robots, and other non-human things. Exophilia may be regarded as the sexual form of neophilia, which is the more generalized attraction to new and unknown things.

(from Wikipedia.org)

Exophilia is a relatively obscure fetish.
