Ray J -- I'm Over Sex Tapes … But Tell Me About Iggy Azalea's!

Ray J says his sex tape days are long past him, but you gotta see his face when we told him there might be an Iggy Azalea sex tape on the market.

Ray J and his manager, David Weintraub, were out in Bev Hills Thursday when we talked to them about the possibility/likelihood of an Iggy sex tape  ... which could eclipse his tape with Kim Kardashian in sales.

His answers are pretty funny.
