LOS ANGELES

DE’BELLA — or Debbie, as everybody calls her — decided late in life to become a porn star. This year she turned 50, time, she knew, to chase her dream.

“I love sex,” she explained, biting into a Burger King special before embarking on her scene for the day at a rented house in the San Fernando Valley. She was wearing a bright pink satin and black chiffon nightie with a matching thong and heavy makeup.

“I decided I wanted to do something different,” she said. “I’d been working behind the scenes, and my friends said: ‘Why not do movies? Have some fun, and get paid for it?’ ”

So she has. Since May, De’Bella (she did not want her real name published) has used days off from her job as an administrative assistant at a sex-related entertainment company, Platinum X, to shoot about 30 scenes, with men mostly 19 and 20 year old.
