I still find myself on IF a lot, but lately I've found myself "finishing" on story sites most of the time. I've always been a fan of erotica (especially longer stories), but I used to start there and finish here. Don't know if it means anything, but having some context to a sexual encounter beyond, "You're hot, I think I wanna fuck you," has been more important. The idea of the random encounter, a workplace hookup, or a lonely, horny neighbor really gets me off.
