Speaking of prostitution...
I've nursed quite a number of AIDS patients who were infected with
the HIV virus because of sex with a CSW (Commercial Sex
Worker).
Isn't it soooo stupid??
Approaching a prostitute for sexual services, probably getting
their needs met and feeling macho about it...
And then, coming down with AIDS.
Well, it ain't macho anymore to lie in bed, scrawny, pale, and
sickly, unable to even feed oneself, having to rely on others to
change your adult diapers for you...
Lying there in bed, day in, day out, praying for death, but
somehow, knowing that death is a sweet release that shall not come
easy...
And then, the shame of having your family find out what you've been
up to! And the unbearable guilt of knowing that you might have
passed it on to your wife!
Time and again, I see this painstaking scenario repeating itself.
It's often the wife and children whom we feel really worried about,
because they're the innocent folks in this.
A man is supposed to be the head of the household. But a lot of
times, they just don't stand up to the responsibilities they ought
to shoulder.
In the process,
they drag down their families with them. 
So, if you're very 'hao4 se4' (ie. hum sup aka sex-hungry), think
of the consequences first!
