Because in real life, it wasn't uncommon that female spies did use sex and their sexuality as a tool to acquire information.

Examples:

1. Amy Elizabeth Thorpe (Cynthia) during WWII 2. Mata Hari during WWI 3. Belle Boyd during the American Civil War

And take a look at this article: http://english.pravda.ru/news/society/sex/08-07-2002/45946-0/

Another well known example was that during the Vietnam War, female Vietcong would act as prostitutes and seduce US troops to enter military bases and acquire intelligence.
