I got it when I was 14. It was my choice. I had other friends who got the rings who were unable to hold up their end of the bargain. But that's the great thing about being a Christian! You are forgiven if you ask for it. It's not like if you get this ring, have sex before marriage, that God will strike you down from heaven.
I have been faced with temptation many times but have resisted. It's hard. But in the end I realize that having sex outside of marriage is not the lifestyle I want to live or a choice I want to make. I believe when I do get married that my decision to abstain will be rewarded.
I don't judge those who have sex outside of marriage. It's their choice. I just believe, that for myself, the best path to a strong and stable marriage that lasts is to abstain. The analogy I like is a piece of tape. If you put a piece of tape on something, and peel it off, it won't be as sticky. Keep applying it and removing it and it eventually loses its stickeness. But put two pieces of fresh tape together and it will be hard to separate.
