Why is it that in our society we have fairly large double standards concerning sex?

Double standards concerning sex in our society are often rooted in gender roles and expectations that have been in place for centuries. These gender roles and expectations can lead to a belief that men and women should behave differently when it comes to sex, with men being seen as more sexually active and women being seen as more passive. This can lead to double standards where men are seen as more sexually desirable and women are seen as more sexually restricted. Additionally, double standards can be perpetuated by cultural norms and values that place a greater emphasis on male pleasure and female modesty.
