Historically, in American society, it’s led to a Gnostic denial of the importance of the body. Separate from that problem, it leads to things like (WARNING VERY DISTURBING SEXUAL CONTENT CONCERNING CHILDREN AT THOSE LINKS) rampant sexual assault of young girls. Christian sexual morality is unique. This doesn’t mean non-Christian societies or subcultures don’t have sexual morality, but it does mean that it’s important to understand when traditional sexual mores are stemming from non-Christian or pre-Christian traditions vs. Christian traditions.
