1. Allow us to use the 'B' word to describe ourselves whenever we need to.
That's what we are. We don't become lesbians just because we date you. Calling ourselves bisexual is not a sign that we're not in it for the long haul with you, anymore than you calling yourself a lesbian rather than [our name]-sexual is a sign that you'll be hopping on to the next woman soon. It's an honest acknowledgement of our identities.
