Internalized homophobia of the majority of American males.
"Yuck, I saw some guys cock. I didn't. I must be gay now."
"THEY forced me to see cock. THEY're trying to turn me gay."
(Never forget the fear of the all mighter and mythic they, them, the different.)
Then there is the whole thing about it being on a screen that is 25 feet tall and that many males are at least somewhat insecure about their size.
Cute then you realize most males are gay, just look at this forum. There are probably only 10 straight dudes including myself here. Just because you like looking at a mans dick doesnt mean all of us have too but that isnt white this country acts like nudity is a bad thing. Amercia is a lost weak country, our priorities are out of wack. The things we should be concerned about ( like 100 million mexians, puerto ricans asians, etc etc ect taking over our coutnry) we would rather worry about somebody getting nude or some other bullshit.
