Many, many women are that last one, I was blown away when I would mention this and shit would end immediately. My current girlfriend actually had a negative/confused reaction to me being bi, she went and talked to her about it, who told her to dump me immediately! She did not though.

But yes, by all means I still told every woman I dated that I was bi anyway just because if it's gonna be a problem then we should just end it. Haven't dated in years though so maybe it's gotten better
