I went to dressing in feminine clothing for a bit but that was mostly due to the fact I was tired of being beaten up and berated because of my very genderqueer appearance (and the fact my partner kept on pressuring me to "dress better"). It had nothing to do with wanting to attract straight men; I unfortunately seem to be able to do that on my own.
I'm bisexual so I've been attracted to all sorts of people. Unfortunately the women I've had crushes on turned out to be straight... >.<
Just to clarify, I haven't formally started the transition process yet. I need to make a gender therapist appointment sometime. Right now I'm seeing a therapist for related issues who is willing to help me, but it's qualified to deal with that.
It's just hard convincing most people you're really male when all they see is a scrappy female... :/
