The funny thing about "straight" porn is that it is amazing how much it focuses on the guy's dick. It focuses on the dick while it's thrusting into a vagina, or getting sucked by a girl's mouth, and then there's always a close-up when it shoots it's "product."

Now, it's commonly known that "maintstream porn" is marketed to guys, so, you have to get the idea that guys - no matter wehther they consider themselves straight, bi, gay - like to see dicks and see them working.

Fact of life folks.
