Before i even begin to talk about the above mentioned subject, let me just relate one real life incident happened to my friend's son (who was 16 then) and his girl friend (who was 15 then). That girl was inpregnated by my friend's son, and she was already 4 months in conception before the news broke, my friend's wife took a firm stand that she did not want to recognize the child, so from then on, no news about the child.
I remembered at one point i had the chance to chat with this young couple, and meekly i asked the girl did she know what sex was about, has she done it, and i even told the boyfriend did he know that sex with minor (under 16 years old) is a criminal offense. Man i tell you, the answer they gave me can even qualify them as sexpert (sex expert). They told me, "uncle eugene, dont worry, we know how to use condoms: and the girl even said this to me," uncle eugene, Ah Khoon is not the first boy i slept with"
May be we must live up to be a modern parents, believing that our teen children know everything and anything that's to know about sex, we condone certain action of them, including letting our child's boyfriend or girl friend putting a night over or even cohibiting, we tend not to tell them that there are rules that cannot be broken, or we just tell ourselves yes they are a grown up now, they know just what to do but the reality is most often than not, these teen children of ours are not as smart as we think they are as far as sex is concerned.
It is indeed tough to be a parent of the present time, and it is not going to get any easier with advent of technology and the easy accessiblity of sexual materials. So i believe the onus is always will be on the parents side, parents shoud give them a home a real home where they can feel that they can express their doubts and pouring out their questions.
P/S : Let start our children right as far as sex is concerned.
