Myla Sinanaj -- I Watched Kim Kardashian's Sex Tape ... While Making My Own

Okay this is creepy ... not only does Myla Sinanaj want to be just like Kim Kardashian ... she had Kim K's sex tape playing during her own XXX romp.

TMZ broke the story ... Myla has gone all single white female and filmed her own version of a Kim K sex tape -- called the "Anti-Kim Kardashian XXX" -- hoping its release will make her millions and land her a reality show.

TMZ obtained a clip of the tape ... it shows how obsessed she is -- you see Myla watching the KK / Ray J video in the background as a Kris Humphries look-a-like bangs her to a fare-thee-well.

Myla does say, "Turn that off ... I can do better than that." But still ...

The one thing that does set Myla apart from KK -- she loses her "backdoor virginity." It's a place Kim never went ... at least on camera.

It's beyond.
