Mysterious Skin (2004)

A gay teenage prostitute and another teen, both from the same small town in Kansas, narrate separate stories from their childhoods. The prostitute's story is about a disturbing homosexual encounter with his pedophile baseball coach, and the other teen's story revolves around an amnesia blackout during which he thinks he may have been abducted by aliens. Later, the second teen finds clues linking the gay prostitute (now living in New York City) to his possible alien abduction, so he tracks him down to finally seek out the truth.
