Fisting...don't know
Female and Transexual.  Don't know, SEC used to advertise that, maybe give them a call.  
Anal Freak:  Terry Lynn will wear you out in about any direction you want to take it.

perhaps I can help...

I'll be in Atlanta on the 22nd & 23rd- not sure if that coincides with your dates or not.

1.  If you want to try receiving fisting, I am honestly an excellent choice.  I don't think I have any TER reviews that are explicitly about fisting, but you can read them to get a sense of my general rimming & (giving) assplay skills.  And I have tiny, tiny hands!  I am no meanie and know how to start slow nd work you open slowly so that we can coax your body into it.  

2.  I do not currently have a TS doubles partner (but I want one!!), but I would be open to doing doubles with a TS lady of your choice if she is an established provider and I could speak to her ahead of time.  I've hooked up with transgender ladies in the past and it was totally hot.  I get what you mean about how you'd enjoy being fucked by the real thing but aren't into men, completely.  A lot of my clients also see trans ladies.

3.  Can't help you with this one, sorry.  Try me in five years though!  I want to work it out because it feels silly that I am so good at helping guys learn how to accept assplay but I can't do it.  However I am working on it slowly on my on time.  

Consider Tori Valentine of Atlanta as well.  She is my bestie and partner-in-crime, just moved to Atlanta recently, and we also offer doubles together.

Migggghhhhht wanna rethink that
