She's a professional sex worker, so Samantha X should know what it takes to be good in bed.

And according to the 44-year-old former journalist, looks aren't that important.

Appearing on The Kyle and Jackie O Show on Tuesday, Samantha didn't hesitate when asked what makes a woman good in bed.

Samantha, whose real name is Amanda Goff, insisted that confidence is the key to sexual prowess.

'It doesn't matter what shape or size, it's confidence. Men don't care about that kind of stuff,' she revealed.

Elsewhere in the interview, Samantha revealed that she is very different in real life compared to her escorting persona.

'Samantha's way more exciting [than Amanda],'she laughed. 'I'm so boring!'

'Samantha is everything a woman wants to be. She's empowered, she's sexy, she's confident... She click-clacks down the hotel lobby,' she added.

The conversation soon turned raunchy, with Kyle Sandilands asking Samantha what she believed his co-host Jackie 'O' Henderson's 'signature move would be in bed'.

Although Jackie was determined to shut down the topic, Samantha said she thought the 43-year-old would be a 'reverse cowgirl' type of woman.

She backflipped on her remark, however, after learning that Jackie has a seven-year-old daughter and has been married for 15 years.

'Yeah, you don't have sex anymore, do you?' joked Samantha.

She then told a story of a 'really gorgeous' client whose wife refused to have sex with him after they started a family.

Samantha added that this happens often in long-term relationships and that many of her clients are sexually frustrated married men.
