totally agree.......

a lot of virgin girls (& some faggy guys too) tot dat sex is ez, just sex.
where 1st time must enjoy with "the 1" + absolutely perfect, romantic setting.

once dis kind girl loose her virginity, she den realized dat the ntgh similar to her imagination (coz there is no such thing as perfect),
1st time is not as enjoyable as she imagine (in fact too pain or fail entry),
& clumsy & dunno wat to do (girls, sex is not as simple as u just lay there.... ).

den she'll realized that it tek a lot of practice to be good & really enjoy sex.
NOBODY IS GOOD, NOR ENJOY THEIR FIRST FEW TIMES.

IMHO,

Guy doesn't want it until after marriage + Girl doesn't want it until after marriage = Good example

Guy wants it + Girl doesn't want it = Sex is just a bonus

Girl wants it + Guy doesn't want it = Sex is just a bonus (rare case)

Guy wants it + Girl wants it = Sex is important

I love your bottom line.
The good example is so hard..
Why should you regret, history down the road, your ancestors have it. Be proud.. It's not guilty pleasure, it's something passed down in our blood to breed and multiply more.. But best is doing it with the right reasons (within marriage) or for those who are not bound by commitment/religion, do it wisely, don't dump babies, at your discretion and do it with your loved bf/gf, it's not a free service, it's a gift and a rare one..

The youtube clip's title is interesting (I asked my chinese friend to translate).

We as guys mana ada "tipu" girls to go to bed with us 
Most will be willing to be to.. 

But be responsible for your doing. Don't throw away babies like garbage or unwanted pets (I don't condone pet or human dumping)!!
