SAFE sex has never been this scary.

A box of Trojans will doubtless suffer from shrinkage when faced with its latest competition: KISS Kondoms, a line of contraceptives featuring the infamous face-painted rock band KISS on the packaging.

The “Rock ‘n’ Rubbers” are the brainchild of specialty condom retailer Condomania (351 Bleecker St., at 10th Street, in the West Village, http://www.condomania.com), who convinced the band to lend their attributes to the safe-sex business.

Up first in the series is Tongue Lubricated ($4.95 for a box of three), adorned with a head shot of bass player Gene Simmons in full makeup – white face with black bat wings around the eyes – with his famous tongue fully extended.

“Sex is always embarrassing for people, so when a guy whips out a KISS condom and there’s Gene Simmons’ tongue hanging out, it lightens up the situation,” Simmons said.

“Some deserving young ladies will get a personal demonstration – lots of them, come to think of it.”

Condomania founder and president Adam Glickman, who started out selling condoms door-to-door at Tufts University in Boston in 1987, was optimistic about the condoms’ potential, saying, “We expect to sell hundreds of thousands of boxes.”

Up next: a possible Ozzy condom, featuring reality TV dad Ozzy Osbourne, and a P. Diddy version.
