It is always a sin to engage in sexual activity with someone you are not lawfully married to. It is called adultery. Read what Jesus said:
But I say to you that every one who looks at a woman lustfully has already committed adultery with her in his heart. Matt 5:28 RSV
[20] And he said, "What comes out of a man is what defiles a man.
[21] For from within, out of the heart of man, come evil thoughts, fornication, theft, murder, adultery,
[22] coveting, wickedness, deceit, licentiousness, envy, slander, pride, foolishness.
[23] All these evil things come from within, and they defile a man." Mark 7:20-23 RSV
Be aware that it is a sin for a man to marry a man or a woman to marry a woman. Again, read what Jesus had to say:
[6] But from the beginning of creation, `God made them male and female.'
[7] `For this reason a man shall leave his father and mother and be joined to his wife,
[8] and the two shall become one flesh.' So they are no longer two but one flesh. Mark 10:6-8 RSV
Satan, of course, wants us to believe otherwise, and he is extremely subtle in his dealings with us:
Now the serpent was more subtle than any other wild creature that the LORD God had made. Gen 3:1a RSV
Between the powerful attraction of sexual lust and the subtle influence Satan tries to exert on us, sexual lust is an easy trap to get caught in. Don’t let it happen to you.
