No, ladies, you haven't died and gone to heaven.

The plus-sized package this male model's sporting behind the cracked glass -- because he's just THAT big -- isn't real.

Sorry.

It's actually comes courtesy of Spain's Unno Anatomic Underwear, which claims to be the first underwear line designed to give men's privates a boost.

Judging by the hunky male model hired to show off his bulky boxer-briefs yesterday in Madrid, we'd say the product works.

Now go put some clothes on, hon. You're gonna put an eye out with that thing.

Meanwhile, shapewear for men is flying off the shelves.
