Teagan did two solid interractial scenes early in her career. Even though she hasn't done any since then, she is OK by me because at least I know she is willing to cross that bridge if the situation is right. I am pretty sure her contract with Digital Playground accounts for her lack of IR these days -- not her own personal boundaries.
EDIT: In fact, her decision to do IR so early in her career speaks volumes - it means that to her "IR" is no big deal: Its just sex where the partner happens to be a black guy. I becha she wasn't thinking about how to "cash in" and hold off on IR for later on. She was just doing another scene and not making a big deal out of it. That's how it SHOULD be.
