Well it's common for surgeons who don't know you to do a consult over the phone. It is an initial consult and nothing odd. If it's for meta they'd have you send pictures, but I don't suppose it matters too much for phallo. (Or perhaps so, no experience with this.)
Oh boy, I didn't know he did free consults. Sounds good. I am looking into someone for meta (though haven't decided even IF I want it).
A good doctor should help you feel at ease. It's normal to be nervous. Telling him up front you are nervous about it might be a good idea.
