I think she owes us a proper anal scene with a BBC too.
But realistically, if she didn't give her ass to Jax Slayer or Slimpoke, who were two of her favorite male performers (as she stated), it won't happen.
With Dredd, according to what I've read, at first she was willing to do it, then she started to avoid him, he also offered her BJ only and she rejected that too. I suspect someone brainwashed her not to do it; I don't have proof of this, but it could have been her agent or VMG. Eliza vs Dredd would have been EPIC.
Overall, I think she and her agent never understood how popular she was. I think she limited herself in her later years from doing many things, and her fans were left wanting to see much more. The way her career ended was regrettable; she practically left through the back door.
