Sex On the Beach Lands Guy In Prison for 2 Years

Hope he enjoyed banging on the beach -- 'cause a Florida man's gonna be locked up in prison for the next 2 and a half years for doing the deed.

Jose Caballero was nabbed for having sex last summer with his girlfriend, Elissa Alvarez outside Tampa. Problem is these rocket scientists were banging in front of a woman with a camera -- and more importantly -- in front of little kids.

Witnesses say they weren't exactly quiet or discreet during the 25 minute encounter.

Both were found guilty of lewd or lascivious exhibition in front of a child, a second-degree felony -- and must register as sex offenders.
