I personally think that you're missing out big time if you don't do the show. It's not very often that pornstars get these kinds of chances to be shown in the mainstream media, and as long as you stick to your guns, and you don't have a complete meltdown, it's going to be good publicity.

It's entirely your decision, but I can pretty much guarantee that people like Sasha Grey and Tyra Banxxx gained a lot of new fans by appearing on the shows they were on. As long as people are talking about you, good or bad, that means that you're on their mind which is ultimately the goal.
