Draya Michele's ex-BF claims they made a sex tape ... and now he's suing to get it back -- because he's worried their skin flick will go public.
TMZ has learned a video is being shopped around to the big porn companies ... featuring a woman who looks a lot like the "Basketball Wives" star -- and her ex, David Miranda.
Miranda filed suit in NY small claims court ... for loss of "private documents." David tells us the private "doc" in question is actually a sex tape.
David says he and Draya were banging from Jan. 2011 to Sept. 2013 ... and have videos meant for their eyes only -- and now he's upset someone is pimping it.
Miranda blames Draya for the alleged footage ending up in the wrong hands.
