Denise's sexuality

Is Denise perhaps bisexual, or maybe even lesbian? I mean there's hints: when she met the hot black witch in S2 got really excited at the thought of her being her new mother. When she told Evie about an actual lesbian she knew at work she again sounded excited. Then in S3 she all but PROPOSED to that fake FBI demon chick. Plus she writes slash fanfiction so she's obviously pro-LGBT if nothing else.

Perhaps that's why she seems oblivious to Kevin's attempts to win her over. Granted they did go on at least ONE date, but HE seemed to be more into it than her. Either she's bi and is more into women, or is lesbian and unfortunately all her crushes disappear or turn out to be evil demons lol.
