I'm sorry. IMO, you did trick them. You are NOT a girl, whether you identify MORE as a girl, or not. Regardless, talking/flirting online or in person with no intention of going forward is called a tease. Nobody appreciates a tease. IMO, a guy who will be attracted to a bisexual GG may have a little more openness (or uncertainty) in his own sexuality. So, not really a guage in what a straight guy would be okay with.
