Those who do not know the "Word of God" refuse to accept what they read, the Holy Scripture talks about to Know a Woman as a sin.
Yes it is talking about sex and about kissing, for those who like what the world likes will minimize what the Holy Bible says they will try to break it down for their own needs.
Do not take this as a threat nor offence but as advice to becoming Holy. For the Holy Bible teaches us to practice Holiness to be Chirst Like not to be world like.
