Many "mainstream" sexually explicit videos target a male, heterosexual audience and

1. portray dominant men with huge erect penises
2. show men ejaculating on women's bodies
3. portray the image that men must "last long" to satisfy acquiescent women.

They portray all of the mentioned.

Explanation:

People who make mainstream sexually explicit videos target males, heterosexual and tries to portray a lot of things in these videos. One thing peculiar with these videos is that they are known to always show men having huge erect penises ready to achieve penetration. They are also known for showing men who would rather ejaculate on the bodies of the female. One thing that is also very easy to see is that men in these videos last so long in the sex act; reason being to guarantee satisfaction from the acquiescent woman.  

low context culture   (lc.):

association:    

relationships begin and end quickly. many people can be inside one's circle; circle's boundary is not clear.

things get done by following procedures and paying attention to the goal.

one's identity is rooted in oneself and one's accomplishments.

social structure is decentralized; responsibility goes further down (is not concentrated at the top).

interaction:

low use of nonverbal elements. message is carried more by words than by nonverbal means.

verbal message is explicit. context is less important than words.

verbal message is direct; one spells things out exactly.

communication is seen as a way of exchanging information, ideas, and opinions.  

disagreement is depersonalized. one withdraws from conflict with another and gets on with the task. focus is on rational solutions, not personal ones. one can be explicit about another's bothersome behavior.

territoriality:

space is compartmentalized and privately owned; privacy is important, so people are farther apart.

temporality:

things are scheduled to be done at particular times, one thing at a time. what is important is that activity is done efficiently.

change is fast. one can make change and see immediate results.

time is a commodity to be spent or saved. one’s time is one’s own.

learning:

reality is fragmented and compartmentalized. one source of information is used to develop knowledge. thinking is inductive, proceeds from specific to general. focus is on detail.

learning occurs by following explicit directions and explanations of others.

an individual orientation is preferred for learning and problem solving.

speed is valued. how efficiently something is learned is important.
