Women tend to be the more passive recipients of sexual relations so how can they be manipulative at the same time?
By determining when the man can have sex with her? Setting up relationship hoops for the guy to jump through?
By not having sex when she wants to (if at all), only communicating she will when he does something she thinks is worth her "giving it up?"
By having sex, and then having certain requirements of him she indirectly communicates are expected since he "got some?"
And her reactions during sex giving the guy certain feedback? e.g. laying there quiet and unmoving like a "dead fish?"
Via moral judgment and social ostracizing and treating sex like a commodity?
