What to do?

[Ringlets]

I just decided to join this site (which is wonderful btw) after reading posts for a couple of days on the outside looking in. I have a problem though, which is why I started looking in the first place and need some advice.

I met someone online and plan going to meet them for the first time next week. I have always ID'd as a femme. Hy IDs as old fashioned Stone Butch. He is ten years older then me and we live two states apart. (I am nervous because I have never posted in a forum so please bear with me -- I am trying not to leave out anything important!)

I really like hym and we seem to have everything in common. We have been talking online and on the phone for three months. I have seen pictures of him. But he has not seen or asked for pictures of me.
Now I am just scared to death. He has never asked me what I look like or how much I weigh. It just hasn't come up. Somehow though during a conversation recently I got the impression that he liked thin girls. That is why I am so nervous now!

I am not skinny at all! I would consider myself fat. I'm always working towards skinny, it just doesn't happen fast enough. I don't hate my body like some do, but I don't love it either. I also have a scar on my face that isn't huge but you can see it. My question is should I just call him up and warn him?
I am not sure what to do and woudl appreciate any advice. Thank you all so much. I'm sorry this was so long!
