She may be the woman who took the record from the woman who the documentary was about.
Actually just googled (my history will be interesting) and she was Annabel Chong and is Singaporean. She had sex with 251 men in 10 hours to make a film but her doing that is what started the "record" race. The film is "Sex. the Annabel Chong Story" but it is depressing as hell, so while it is very interesting, be aware that it is a horrible watch.
Then I read about that woman you mention and it turns out that there were THREE women competing for the title, how many men turned up for that?! Its just so so awful that there are so many grim disgusting men out there........and they wonder why we dont like them.
