Although Amy has one of the hottest, if not the hottest bodies in porn she'd be one I would put ontop of the "defenitely not a size queen" category. Her first few scenes were horrible in terms of her "taking it", even though the guys seemed to be going out of their way to be gentle.
And now that her F-ing on camera skills have improved dramatically she still doesn't seem to going for the biggest dudes or into trying to deepthroat or get it balls-deep.
Tera Patrick on the other hand has repeatedly proclaimed her love of the huge ones and her distaste for the small. I forget exactly what part of the show she said it in but you can hear it from her first hand on this episode of Loveline:

Drew was kind of displeased with her opinion because he's always trying to downplay the girls-liking-it-bigger phenomenon.
