Maintaining your virginity is one of the greatest boosters to your self esteem. It gives you a sense of pride as you walk around knowing you've got something the world has never touched. You're the definition of a keeper. You've kept your purity. It also makes other decisions of life very simple: sex before marriage? Sorry. I've kept myself by a vow and I can't just break it.
And when someone comes at you with the lines of 'If you love me prove it by sleeping with me,' you'll be ready with a commonsense stopper. 'My proof of loving you is marrying you and giving you what I've never given the world, for the rest of our lives. Your proof of loving me should be respecteding my vows and not pushing me down a path I'm uncomfortable with. And in any case you're already disqualified for the very request of sleeping with me because it means you're not living by vows of celibacy like I am. And I only want to marry my kind.'
For parents, many young people lose their virginity to workers and older relatives who sneek on them before they understand the world. Keep an eye and educate them from early on. Do not exclude boys because their predators are on the loose too, and they're taking advantage of the fact that parents tend to be more relaxed with the safety of boys than that of girls.
Make all the children sing that song when they're 3: 'These are my private parts, nobody should touch, nobody should see...' Also, because of todays attack of pornography on mainstream media, you also have to sensitize them against nudity and indecency. For the boys, be the one to teach him about wet dreams and how different they are from masturbation.
What does all this mean? That you must be learning ahead of your child before they reach every stage so that you're equipped. Today's parenting is not just about paying rent and school fees. You must also serve them mental diet. And no, you can't escape by getting them a phone. That's another disaster by its own.
