Hrmmm... that is pretty different than Syd.<br/><br/>Basically (and your call if you all know this, you've been with her for awhile) Sydney's power comes from lust and desire, the more ardent the desire the more easily her power comes.  In situations where sexual needs are so high that rape becomes probable her power flows the strongest.<br/><br/>However, if sexual desire is being fulfilled, it becomes really hard for her to draw on her power.  So if she were surrounded by enemies with NO sexual desires and none of her friends were feeling frisky, she would have a much harder time using her magic.  Significantly more commonly, if she were actively being sexually assaulted then the desire would shift into passion and relief, which Sydney can't really use...  (Yes, this means she is really good at stopping a would-be rapist, but really bad at defending herself once the violation begins)<br/><br/>So, yeah... while Nuria's power can increase during sex, while sex will weaken Sydney, she gains power from teasing and flirting and leading people on.
