Watch the series “The Bisexual” and see how the tribe feels betrayed when the lead character finds herself wanting to experience hetero sex and starts dating a guy. From my experience, gay folks often respond negatively to any hint of bi- or pansexual curiosity, let alone activity. So, your fears are well founded. Then again, for many, sexuality is fluid. I’d worry more about hurting the lady you’re attracted to getting hurt than what any of your tribe thinks.
