Can you suggest some resources about trans-sexuality and/or sexual reassignment surgery?

I’m currently writing a story about a transsexual man female to male right after his sexual reassignment surgery. The story takes place several years in the future so I am taking some medical liberties, but I realized how little I know about trans-sexuality and the actual physical transformations that take place. If you can suggest any resources that deal specifically with female to male transformation, that would be most helpful, but really any resources are appreciated. Thanks collective!
