What a relief to read.
I'm the same person all the time, but i do change between feeling masculine or feminine, and sometimes it even surprises me, exciting and frustrating at the same time.
What scares me is that one time, when i talking with my female friends, we came into the topic "how we would be if we were men". I was sitting and trying to imagine myself as a man, and i really liked it. I got all frustrated about being a woman, and at that moment i just wished i could change body , like you change your hair. I hope someday in the future you can be a man on monday and a woman on tuesday, if you know what i mean, it would be fantastic.
But on some rare occasions i feel extremely feminine and love it, but otherwise i feel like i fail to be a woman at times, i've tried wearing some really feminine clothes where i felt like a transvestite, there's often a feeling of being akward, maybe because i'm not wearing exactly what i would like to wear of girly clothes, i don't know, but it's frustrating.
Am i androgyne or bigendered? Btw, sorry if my english is poor.
