I have a question for the het men reading.
I've noticed that several of IACB's comments on porn mention a division or difference between, as he puts it, "fans of girl/girl" and "fans of guy/girl." This surprises me, as every mainstream porn movie I've seen has included scenes involving women having sex with women and scenes involving women having sex with men.
But from the way I read (and very possibly misread) IACB's comments, there are two distinct subsets of audience, and they don't like and want to see the same things. They're described as two camps, sometimes even two feuding camps, in an odd way.
I don't think there's anything odd about preferring one to the other, or even preferring one exclusively, but I can't say I've ever seen or heard this mentioned by any other straight male porn user that I've known. I always had the impression most liked both, and some had a marked or even an exclusive preference.
So... how does this work? Do most men choose a side? Do few people watch, or like, both?
