I don't have a problem with the lollipop or tape analogy. But on the other hand, there needs to be teaching about being made a new creature in Christ Jesus. There is redemption.
The tape analogy makes sense, since there is some research indicating that women with multiple sex partners prior to marriage had a higher rate of 'marital disruption.' (Teachman, 1990, Journal of Marriage and Family.)
It is good to teach the need for modesty in dress with a mind not to tempt others. But boys need to be taught modesty, too. And those who choose to commit fornication in a situation where much flesh is displayed need to be taught that they are responsible for their actions. Men need to be taught self-control, and encouraged to be holy, to desire to please God and not sin against the Lord, to treat young women as sisters and older women as mothers.
A passage I have noticed on the topic of sin and fornication is that Esau is compared to a 'fornicator or profane person' in Hebrews 12. When he would have inherited the blessing, he found no place of repentance. In the account, Isaac couldn't change the situation and give the blessing away he'd already given to Jacob. Esau missed out on a big blessing.
I can't think of other passages where it says that God will punish/avenge against believers except in regard to fornication in I Thessalonians 4. It is written to believers and warns against fornication, warning that God will punish (or be an avenger of) all who defraud their brother in this way.
Here is an analogy I have heard. Is this too crude for church?
"From a worldly perspective, who would you say was lower class, a prostitute, male or female, who made $3000 per client, or a prostitute who made 25 cents?
The Bible uses the same word for regular sex outside of marriage that it uses for having sexual relations with a prostitute. If a prostitute who charges 25 cents is lower class in your mind than one who charges $3000, what about someone who does it for free?" Our society has a lot of free whores. It's all whoring. If it is outside of marriage, it is whoring around, whether money changes hands or not.
