Hmmm, I tend to identify with characters even in PWP. As strange as it may sound, that's why I prefer slash over femmeslash. I simply don't identify with the female characters as much as with the male characters, maybe with a couple of exceptions. As for kinky porn, I identify with the Dom, but there's a partof me that identifies with the sub as well, and I do tend to write from the sub's POV more often than from the Dom's. I deeply cherish the sub too :)

Guess I wasn't of much help :P
