A privilege a girl or woman attains by committing to a formal relationship with another person. Similiarly, there are boyfriend privileges.
Example 1:

Anna: Can you drive me to the airport this Tuseday? I have a meeting in New York.

Joe: Sorry, my project is due Wednesday. I know we're having sex but putting you ahead of that is a girlfriend privilege.

Example 2:

Joe: Pardon my pushingness, but would you like to engage in a sexual act in the very perimiters of this sanitary facility?

Anna: Sorry, that's a boyfriend privilege
