I am not sure if there would necessarily be an advantage for one individual to another individual in a sexfight. In a sexfight there are many factors that would come into play. Sensitivity, self control, determination, etc. However, Experience would also play a significant factor. I would expect that most hollywood actresses would not have the same level of experience as a porn star. Especially with the kinkier side of things like a sexfight. I mean how many of the hollywood actresses would have ever been with another woman? Some perhaps. But probably not most of them. Where probably the majority of Pornstars have been with another woman. They probably have a better idea how to drive another woman wild than the average actress would and probably have a lot more experience controlling their own arousal. So overall, I think you would probably have to give the advantage to pornstars for this one.
