I took that as some kind of version of that "after-a-couple-of-dates-I'll-tell-him/her-that-I-crossdress" approach... which is the natural thing to do and don't hurt anyone, isn't it? ^ ^
I also think you tricked them a little bit, but no biggie... guys tend to give girls more attention... but to be sure you'd have to set up a new profile, identify yourself as bi-gm and see if there's substantial change from this try. I believe it would, also the tone would be different... but who knows?
(great that your pics passed. I mean, we knew that already, but that was a nice test indeed ^ ^)
