This is a response to some guy stating he doesn't appreciate a girl looking into the camera during a M/F hardcore scene. You brought up a few great points about when and how it happens and why a guy might like it, but I feel like you forgot one of the most important reasons it has appeal. Some seem to think it somehow takes away from the fantasy of the viewer being the guy inside the film, unless, of course, it's done entirely POV. That the chick is getting off on the guy, and we want to be that guy. Yes, there is a voyeuristic quality to the girl glancing at us, but more importantly, I feel, is that when she's glancing at us but getting off on the guy, it's like the girl is saying to the viewer, "Do you like what you see, because I'd rather be fucking you than this guy in the video. I'm imagining it's you and not him giving me pleasure, and the only reason he gets me off is because unfortunately you're not here to do it for me."
