'I'm the world's most successful male porn star. But I struggle to satisfy my wife.'

Porn star Keiran Lee is heralded as the world’s most successful male porn star.

His nine-and-a-half inch penis is insured for $1 million, but there’s one problem: after a hard day at work, the 33-year-old can’t…err…’perform’ when he gets home to his wife.

In an exclusive interview with The Sun, Lee revealed he is “pathetic” when it comes to making love to his wife.

“At home with my wife I have to apologise, I am pathetic in bed. I’m like a two-minute wonder,” he said.

Keiran, whose real name is Adam, can earn more than AU$5000 a day when he is filming scenes and producing, and his work has seen him travel to Spain, Russia and France.

But despite his unconventional career, Keiran describes his life at home with wife Kristen, a former porn actress herself, as “boring”.

“Adam and Keiran are two different people. At home I am Adam, I love my football, I am a normal guy,” he said.

Keiran and his wife have been together for nearly six years, and have a two-year-old son, Max, together.

“Being with her is completely different to what I do at work. That’s just my job,” he said.

The male porn star admitted he wants to move out of acting in films and into producing for the porn industry before his son is old enough to understand his job.

“Once I got into porn I thought – it won’t be fair on him or her, everyone will look down on them. I just didn’t want my son to get bullied, because of the career that I chose,” he said.

“But I have never regretted it. I give him the best of everything. My mum was a single mum and she worked every hour that God sent to give me and my sister the best. I want the best start for my boy.”
