My husband travels to China alot and I have never been. Do I have to
worry about the young aggressive chinese woman and my husband. What is
the social interaction in mainland China and is this a common problem
with American men traveling and doing business in China.

Hi Stella,
China is like anywhere else.  
I don't what other kind of answer you might like.
Maybe someone could tell you that the "young aggressive woman" in x or
y country is more of a potential problem, but what does that tell you?

If you notice that your husband's collection of Adult Magazines
switches from caucasian women to Asian women, I'd be very worried.

Not necessarily, Cynthia-ga.  If a man reads Hustler or whatever at
home and doesn't play around, he could just as well enjoy mags with
Asian women without doing so, having just learned through exposure
that they can be attractive too.
I went to China with a friend who swore that he didn't believe there
were any attractive Chinese girls (not having ever seen any), but
within a day, he had changed his mind  - without "following up" on
this new appreciation.

myoarin,

Thanks for the heads up, you do have a point, but on the other side of
the coin, it _could_ be a sign of trouble, don't discount that
possibility...

Cynthia-ga and Stella,
Just one man's opinion (should have thought of this in my previous comment),
I very much doubt that a man would be "flagging" his interest in other
women by expanding his collection of girlie magazines.

Hi stella333,

I understand your concern and will submit my opinion. It basically
depends on your husband. Women there are not going to throw themselves
at a American Businessman.

The part you should be concerned about is that types of "legal prositution" exists.

Basically, if you husband wanted to cheat on you without you knowing
he could. Sorry to be harsh.

Googling "prostitution + china" will reveal the first link to
WorldSexGuide (NWS) so I will not post the link.

You can find actual american business men talk about their experiences
in china or any country at
http://www.worldsexarchives.com/world_sex_guide/5China.html

From WSA "This web site is an interactive discussion and archive
database dedicated to providing information about prostitution, escort
services and sex tourism."

I would have a discussion when he gets back.

When he gets back have a little "chat" with him. Does he drink? If he
does, and gets drunk, the truth should come out.
