Male bodies are often predictable-the cocks, if not possessing rare magnitude or look, appear just similar to each other. In gay porn, what is emphasized is the feeling of tension and building up the lust between the two.
It is about showcasing the voyeurism involved in female anatomy rather than the actual sex between the man and the woman. It is not the same as when it is done by heterosexual couples, because in straight porn it is usually about flaunting the bodies of the women. One of gay-popular aesthetics is shower sex.
