World's Oldest Prostitute Twins Reveal Top Tips for Keeping Your Man Happy

 Sister act: Louise and Martine Fokkens were the world's oldest prostitutes when they retired last year

With more than 100 years experience between them, there's little that former prostitutes Louise and Martine Fokkens, both 71, don't know about men. Now the pair, who retired last year, have revealed the secrets of keeping your man happy - both in bed and out - in an exclusive interview with MailOnline.

'What I've learned about men is that when they [men] drink, it's not good. I have also learned that people need prostitutes - it is normal and we should respect it. 'Men are born this way [in need of sex]. There isn't a problem and it makes me mad when people don't have respect for what we do.'

 'Be easy, listen to what he wants - always. When we started in the 1960s, we learned the same thing from the older women we worked with.

Every man wants something different and that's the real game - finding out what they want.

 What about men who cheat on their wives with prostitutes or other women? The ladies say:

 'They want to be free. Their wives won't have sex with them even if they love them.
If you really want to meet a man and keep him, you need to be yourself. Always be yourself. This is what we learned when we were little and it's true. But also you must have respect for other people and listen to other people.'

Between them, the Fokkens twins have slept with 355,000 men during careers that began more than half a century ago. The sisters, who are famous for their trademark matching red clothes, first turned to prostitution aged 20 after escaping violent relationships.
