Equal opportunity dominatrix

Grinning hugely, Jenny sat back down at the computer and looked at more options. There was so much! A vast array of menus, tabs, text boxes and who knows what else. One section caught her eye:

SEXUAL ORIENTATION
Male: 90%
Female 25%

This section had some sliders, with which Jenny could presumably change those numbers. They seemed accurate to her. She was definitely into boys, but occasionally had had naughty thoughts about pretty girls, though normally she found the thought of lezzy sex a bit unappealing. Well, a dominatrix shouldn't discriminate. Smiling, she slid the "female" bar up to 90%.

She didn't feel any different right away. How to find out if it worked? She decided the easiest way was to look at some internet porn. After a few minutes of browsing, she decided it had definitely worked! She was now bisexual.
