Side note: never imagined there were so many bi-women in here
She is physically atracted to both men and women. But she still remains mentally loyal. Now, the only thing you have to worry about is: if she does want, once in a while, to satisfy a physical need for women, both of you should attempt not to share each other with the other woman, but actually share the other woman between yourselves
if everybody agrees of course. Thus you can get involved as well.
Problem is, partner change, specially among women (Brandye correct me if I'm wrong) can have higher risks of STD treansference, because there are more people involved and, for what I know of W-W sex, contraceptive measures are difficult to employ (Brandye is going to kick my butt on this one, no doubt...)
