Turbonympho women, such as the kind who join the military, can casually develop and drop sexual preferences to get what they want, depending on the environment they're active in. I've known many women who were straight at one point, lesbian at another, and then eventually bisexual. They change their sexuality to suit their needs, and barracks bunnies are no different. It's not just dicks they're sucking, they're also sucking down oysters.
