@bellamente,
Hmmm Bellamente, there is nothing here to imply that Sweet Katy wants to live by the bible understanding that "fornication is a sin". If you read her post, she is doing it for her parents.
Personally, a 17 year old is just about at the age that she needs to start making decisions for herself. In less then a year she will be a legal adult. Seventeen is the right time to have adult, meaningful adult relationships.
I think your advice that she get married right away is horrible. Seventeen is far too young to make a lifetime commitment. The statistics are clear that people who get married young are far more likely to get divorced (or worse).
For most human beings, sex is a normal and healthy part of a healthy intimate relationship. Most people start having sex at about the age of 17, and most people have a fine meaningful experience having sex far before they are married.
Hopefully Sweet Katy has access to information about birth control and responsible sexuality. One problem with the unrealistic rules of religion is that people "fall" into sex, rather then enter a sexual relationship responsibly. This is why unwanted pregnancies happen so often with religious teens who have promised to abstain from sex.
The no sex before marriage idea may have worked 100 years ago when we lived shorter lives, worked on farms and had simpler religious ideas. These days people value education and careers and freedom. Abstinence before marriage really doesn't sense any more.
