Long, passionate kissing definitely should be avoided.And French kissing is out--it's purpose is to be passionate and suggestive, not to express pure affection (plus, the stuff with the tongues just seems tacky, in my opinion).If you put your arm around someone on a date, what are you saying (without using words)? And that's exactly why we have to be careful - because we could be telling lies with our actions.This is a major reason why people get hurt, and why there's heartache.
The experience of same-sex attraction is a complex reality for many people.
When I was 16, I remember a Church leader talking to a number of the young men and telling us not to neck or pet when we went on dates.
I nodded my head, and then went home to look up "petting" in the dictionary. Then I looked up "fondling" and read something about touching.
Too many of them are shocked, or feign to be, when told that what they have done in the name of petting was in reality fornication. The devil knows how to destroy our young girls and boys.
He may not be able to tempt a person to murder or to commit adultery immediately, but he knows that if he can get a boy and a girl to sit in the car late enough after the dance, or to park long enough in the dark at the end of the lane, the best boy and the best girl will finally succumb and fall.
