I did this, doing it now w/ Allison. No trans chatroom, so I was Allison in lesbo chat. I passed too. Grad work in lit. had me looking at women writers, characters. Women often published as men. Women characters often had "male" traits. Easy to turn all that around, male as female.
Change your avatar in here, change your gender listing. I'm pretty much "really" Allison, here and there, FB, newspaper forums, other sites.
But mostly the big break from the angst, obsession, preoccupation . . . deciding that it's me and it's OK. I'm no longer juggling two persona. Less fragmented, more integrated, happier, more grounded, authentic.
Complex, colorful, complicated, diverse, many faceted -- but just ONE me.
