I made a male facebook before I knew that the word for me feeling like this was that I was actually trans. I made it under a completely different name to my birth name, and I added the friends I made off some chat websites and MSN on there

No one I had seen in real life knew about it, and I was pretty much living as 2 people. I talked to these guys sooo much! Eventually we met up, but yeah

Then when I found out about being transgender...which was probably 5 months after first talking to them, I made a male facebook for my real self. I didnt have the guts to add my real life friends to that facebook until I left the school. And that was pretty much how I came out to them all, by adding them on that facebook

They dont talk to me anymore, but ohwell haha, I made new friends!
I reckon you should go for it, and have the facebook you want
