Preview of Alien

A space alien experiences a bizarre and rather unfair encounter with the Department of Justice, ends up exiled to Earth, taking over a body (Afghan-Canadian woman) in a state of clinical death. Things get worse as the two personalities, Afghan and alien, end up duking it out for dominance in a series of misadventures which only get worse.
As for sex in this story, the characters talk of sex in general, for purpose of comparing and contrasting Earthling and Alien mores. They negotiate to have sex, purpose to demonstrate their level of angst and problems. There are no actual scenes describing sex.
