(Pro 6:32 KJV) But whoso committeth adultery with a woman lacketh understanding: he that doeth it destroyeth his own soul.
I will be honest with you. I have never been seriously tempted to commit actual adultery. I am sure I have “lusted in my heart” to a degree and Jesus says that is just as bad. But to actually go out and get physically involved with a woman I was not married to? Never happen. It was hard enough getting involved with the woman I married.
Maybe you are different. I think that most people have drunk the kool aide sold by the movies and literature and think that people are more sexually active than they are. The point here is that the standard of God is simple, clear and eternal. Adultery is a sin. Adultery is sex outside of marriage. Marriage is between a man and a woman.
So? Be aware that there is a massive campaign to destroy the institutions of marriage and the family. Don’t buy into the lie either actively or passively. The lie leads to destruction of you as a person, the family you have and the society you live in.
