Final answer:
Sexual activity is a personal choice and can vary among individuals. There is a double standard that imposes different expectations and restrictions on men and women when it comes to premarital sexual activity. Research has shown that both men and women are interested in and engage in sexual activity.
Step-by-step explanation:
The question you are asking is about sexual behavior, which falls under the field of Biology. In terms of who engages in sexual activity first, it is not accurate to generalize and say that either men or women do it first. Sexual activity is a personal choice and can vary among individuals.
It is important to note that societal norms and cultural beliefs can influence attitudes towards sex and may create a double standard. This double standard often imposes different expectations and restrictions on men and women when it comes to premarital sexual activity.
Research has shown that both men and women are interested in and engage in sexual activity, and the number of sexual partners can vary among individuals. According to a Centers for Disease Control and Prevention (CDC) survey, on average, women tend to have fewer sexual partners in their lifetime compared to men.
