God created sex to be enjoyed, but gave it perimeters for GOOD reasons. He didn't say enjoy sex in marriage, and not outside of marriage, just to be a giant cosmic kill-joy.
I like this analogy: FIRE is beautiful in a fire place... keeps you warm and cozy on a cold night... cooks your food... and there is something so comforting, primal and mesmerizing about watching the flames... BUT that same fire OUTSIDE of the fireplace is devastating. It will consume and destroy in horrific ways.
But, God's commands aside, we're talking teens... First of all, they are RARELY responsible. And MOST of the time the "consenting" is preceded by a great deal of pressure or seduction. Both sexes are guilty, and it equals MANIPULATION.
"There's nothing wrong or unhealthy about premarital TEEN sex, if it's two loving, consenting, responsible individuals... !?"
THAT kind of thinking ^ is wrecking havoc on individuals and our society as a whole. Epidemic STDs, the greater emotional trauma of break-ups, unplanned pregnancies, single parent homes (statistically poorer), abortion (women KNOW they are killing a baby but feel trapped...), girls giving in and then feeling used... guys being manipulated and controlled... And the casualness that develops can turn sex into something as significant and meaningful as a good belch.
The vast majority of young relationships are NOT forever. Sex is meant to be "glue" in a committed (marriage) relationship. When it's part of a short-lived crush it can tear... the damage to the heart when the relationship breaks up is much greater, especially if you are also left alone with an STD or the guilt of an abortion.
BTW - Being OLDER and having volunteered in a crisis pregnancy center, I've heard many stories... I also have a cousin that got PG at "sweet 16." She was a cheerleader and her relationship with a linebacker on the football team was "loving, consensual" and devastating. It took her 10 years to get her life back on track and she'll never get back what should have been a carefree youth.
I just wish Spider-Man books would not perpetuate or glorify the minefield of premarital sex!
Lecture over... As you were.
