Final answer:
The question involves sexual practices which differ among groups, with a trend indicating that married couples have more frequent sex compared to singles, with 27 percent of such couples in their 30s engaging in sex at least twice a week.
Step-by-step explanation:
The question touches upon the topic of sexual practices which can vary widely among different groups of people. There's a trend observed in sexual behavior that suggests married couples engage in sexual activities more often than singles. Specifically, a study entitled the National Survey of Sexual Health and Behavior (NSSHB) from 2010 found that 27 percent of married couples in their 30s report having sex at least twice a week.
This data sheds light on the sexual behaviors and sexual attitudes of a demographic segment of the population, potentially reflecting the role of intimacy and commitment in influencing sexual activity frequencies. It's important to note that the diversity in sexual preferences and behaviors is vast and complex.
