19-Inch Penis Man--Vivid Says Correctional Surgery's On Us

Roberto Esquivel Cabrera -- the man sporting a 19-inch penis -- just got an offer that could change his life...and the way he walks.

We're told Vivid honcho Steve Hirsch offered to pay for medical treatment on Cabrera's two pound penis.

Apparently Hirsch was so shocked by the pics of Cabrera's penis, he agreed to pony up the surgery loot, even if they couldn't strike a deal on a sex tape.

FYI ... some reports claim Cabrera only has a 6-inch penis and the rest is excess skin.
