When straight guys see a penis in a movie....?

I guess when the males closed their eyes it was either "embarrassing" or just something they didn't want to see. Not all people watch porn, though, either. In some cases the "embarrassment" feeling would feel like if you brought your computer into the theater, hooked it up to the big screen, and started watching a porn flick while all the seats were filled with people. In most cases guys/girls prefer a private environment to watch pornography and please themselves without feeling shameful or judged. Being surrounded by people while watching porn I would imagine could be humiliating especially if they started giving you nasty looks and disgusted faces.
