Sex Sent Me To The ER promo

THE first time Gregg Casarona ever had sex, the walls didn't just shake - they shattered.

The 200kg project manager was 21 at the time and had been dating his girlfriend Jen Gerakaris for about a month when they decided to take things to the next level, The New York Post reports.

Ms Gerakaris was 22 and living in her parents’ Long Island, New York basement at the time. She made her move by stripping down to her bra and panties and waiting on her bed until Mr Casarona got the hint.

“I knew he was a virgin and I honestly didn’t care,” Ms Gerakaris says. “We were dating for a little while and he hadn’t put any moves on me yet so I made a move.”

When things began to heat up, Mr Casarona thrust the 50kg Ms Gerakaris backwards with all 200kg of his girth. And Ms Gerakaris’s head went right through the basement’s sheet-rock wall.

“My initial reaction was, ‘I killed her,’ ” Mr Casarona tells The Post. “‘This is my first time. And Jen is dead.’ ”

After a couple of terrifying seconds, Ms Gerakaris slowly pulled her head out of the wall and looked at Mr Casarona incredulously.

“Why’d you stop?” she asked.

“He looked like he was about to have a heart attack,” she says. “So I just wanted to lighten the mood.”

But Mr Casarona was shaken and insisted on taking his lover, who started to become dizzy and nauseous, to the hospital, where she was diagnosed with a concussion.

Their story will be featured - with a less-steamy reenactment - in the premiere episode of new US TV show Sex Sent me to the ER.

The couple stayed together for four more years after their ER trip and remain close friends today. Casarona, now 28, has since dropped 100kgs and Gerakaris, now 29, has a new boyfriend who knows about that wild night.
