"Transsexual Versatility" - I'd like to be able to pick top or versatile, and I expect you top guys might like to be able to pick bottom or versatile.
"Transsexual Cock Size" - I'd like to be able to check three boxes: 7-8, 9-10, and 10+.  (IDK, I might max out at 9, but I'll never know for sure until I try!)

I don't suppose TER coding staff would make a priority of it, but it would be "nice".

All I Want For Christmas Is A Tall, Busty, Hung Top Lady

I agree, should be able to check a couple of boxes for this.  

Id like to bring up another problem though, cock size isnt always accurate. I think it relies on the initial reviewer to assess, which in many cases they are wrong.  

Case in point, Alexita in Long Beach. She is fun but she dont got a 9 incher. Not even close.

Unfortunately, I don't think anything will be done about, this topic has been brought up many times in the past. Ways to improve the site, different options etc., but it is what it is.

I find very few providers are honest if they’re top or bottom only. They even lie to themselves. You get sessions where they can’t stay hard but say they top. You get ones where they’re disappointed and not really into it when you want them to bottom. The details in the review will still be the best way to really know the answer to these questions.

It’s clear and routine for providers to overstate their versatility and also the details of what they will do. I wish we could hold part of the donation back until the provider does what’s expected.
And that’s not even mentioning cock size, wjich is generally way off.
