Yes, please. Variety is always part of the pleasure. I will say this - having had a few experiences overseas, especially in Europe, I am partial to American ladies or at the very least ladies who are in America.
Exotic can mean a lot of things - do you mean something "ethnic" or is it more exotic in terms of activities? Sometimes I love the cheerleader, sometimes the mysterious seductress. I have even found a few ladies who could really play a lot of different roles quite successfully. now that is a kind of drama I can appreciate.
Is it your implication that America doesn't have both? Unless you are referring to a Midwestern farmers' daughter I'm not sure how to define the all American girl without including our exotic beauties. That is good for me because I like to mix it up!
