Very interesting post, as a pure consumer of porn I was only made aware of the large number of female who won't do IR when I started reading up on certain performers. I often wondered what is that all about.

Is it marketing, strictly preferences, fear, or simply people creating certain niches within the industry? Is it old fashion sterotypes? (all black me secretly want to fuck white women and when they do the women tend to go crazy)

Is there truth to the notion that it kills careers? I don't think we can use Jenna as a gauge because by most if not all standards she has excelled past any old preconceived notion of porn stardom. I think maybe that question can best be answered by some of the porn girls who post reguarly to have an honest discussion of the following points
1) was it ever recommended that you not do IR and if so what was the rationale used. and further more did you challenge that theory or simply take it to heart
2) did you start out not doing IR and now you do, why did you decide to? what were the real reasons you didn't?
3)what was the actual status of your career before you started IR? What was it after you did it? Has it effected the roles you have been offered?

I really think that this can best be answered by those who went through that. the rest is simply and will remain speculation.
