Re: Why is 18 improbably old?
"I know of no-one who has regretted waiting"
A lot of youngsters before the 1960s got married because that was the only way UK society allowed you to have sex. Sex education was almost non-existent - basically "just say no" - and contraception was a taboo subject. So the result was a quick couple of kids, or more, and often a loveless marriage when the lust was satiated. Divorce was also nigh on impossible for most people.
Again - that's a different problem.
The lack of decent sex education is an issue - and frankly I don't envy anyone charged with providing that (and am not particularly looking forward to those discussions at home either) because most of the current generations never had a decent education it makes it much harder for us to talk about - and therefore harder to educate the next generation... ad nauseam...
Don't get me wrong, sex is great - but the general presentation from the media is absurd.
