Yes, while we both know all about the inherent stigma of being bi, your situation is different from the get go, as bisexuality for a woman is looked upon very differently than it is for a man. Or, at least, that's been my personal experience.
Maybe I'm wrong, but I doubt that any self-declared lesbian has ever approached you and said, "Come on, you're gay! Why don't you just admit it?" Or, "I don't have any issue with you being bi. It's just that I would never date a bi person."
If I'm wrong about that, I'd love to hear about it. Peace.
