It bothered me too when you said your daughter couldn't be genuinely bi because she was feminine. Gender identity and sexual orientation are separate issues. Think butch gay men.
I think OT's concern is the negative construction you (unintentionally, because don't sound at all homophobic) put on it-- sexuality the result of trauma = mental illness.
I hope that makes sense. It is only natural given the timing you would wonder, but take care not to let your D know what you think about it. Only time will tell if this is a fad, or who she really is.
