just be straight forward with the ladies, while I am sure they will accommodate you, if not they will help you find someone who can. and if you go to Inez/Monas you can talk with Louis/Peter/Anna and I am sure they will get you a head start with that too.
as for a suggestion I would have to day Jessy off the top of my head (one of my favs). she has plenty of reviews, and I seem to remember seeing a couple from some of the disabled guys. but have also seen it first hand with a guy at the bar waiting for her, seemed like a regular, and she was right out there to help him with a smile as always.
I'll just drink, cuddle, and play with their boobs.
Mila or Jessy might be your girl (and both together should cure any ED). honestly, wouldn't be a bad party even if that was the whole review.
