I was on the verge of writing a post on being aware of underage girls but while researching for the legal age of sex workers, I find this link (Hk action group) and it is a pretty interesting read. I've extracted some of the more relevant portions:

Is escort service/sex work illegal? Is “using prostitutes’ services” illegal?

This is not illegal if a sex worker hold a valid Hong Kong residential ID card (not limited to other conditions of stay), and is performing the trade in a private environment. Participants of heterosexual and female homosexual sex trades must be at least 16 of age, and male homosexual sex trades must be at least 21 years of age.

Are one-woman apartments illegal?

No. According to Hong Kong law, it is not a criminal offence to provide or receive sexual services. Under current legal interpretation, a “vice establishment” is defined as (a) the premises, vessel or place are or is used wholly or mainly by 2 or more persons for the purposes of prostitution; or (b) the premises, vessel or place are or is used wholly or mainly for or in connection with the organising or arranging of prostitution. According to law, it is not an offence to engage in sex work individually. Current legislation compels sex workers to work alone in a private space, hence, sex workers have to face risks alone (i.e., robbery, murder, violence, rape, etc.)

Is “street-prostitution” illegal?

If a sex worker solicits clients in public spaces, she will violate “Soliciting for an immoral purpose”: Crimes Ordinance Section 147(1), “A person who in a public place or in view of the public- (a) solicits for any immoral purpose; or (b) loiters for the purpose of soliciting for any immoral purpose, shall be guilty of an offence and shall be liable on conviction to a fine of $10000 and to imprisonment for 6 months. (Amended 69 of 1990 s. 5)” Key points from this section focus on “immoral” and “soliciting”. Hence, placing sexual services as immoral acts, and is continuously used in the courts. We believe the courts have no reason to be involved in voluntary sexual behaviors of adults, make moral judgments and apply criminal standards. Sex trade is one’s sexual desire and behavior; no one should determine another’s guilt based on an individual’s sexual desires and participants agreed upon behaviors. The interpretation of sexual services as immoral must be stopped immediately.

In terms of “soliciting others”, the law only targets the “solicitors” that can be the ones providing sexual services or their clients. Whether the sex trade agreement (immoral purpose) is successful or not, the solicitor may be charged. Unfortunately, police tends to enforce this more on the sexual service providers (sex workers). Rarely is the law enforced on the clients, hence the law enforcement process is filled with unnecessary and unfair moral judgments.

May I just add the following conclusions (please correct me if I'm wrong) based on the laws for punters:

1) Walk ups - perfectly legal so long as there is only one girl present

2) Hotel walk ins - grey area for punter. Girl is engaging in an illegal activity, unless she is a local resident or on some kind of work visa and doing this part time)

3) Street walker pick ups - punter can be busted for soliciting.  Girl is engaging in an illegal activities. I guess the definition of soliciting is important. Let the WG make the first move. I'm not sure how the punter can protect himself, audio recording? Vid recording?

4) Massage/ Saunas with HE - Illegal establishments if caught with pants down. Not sure about client, most likely can get away with 'I was lost in the moment, or, I'm not aware and was entrapped'.

5) Pick up pubs - Clearly legal. 3P, 4P etc should be alright at the hotels, amongst consenting adults.

Thanks for the above but please do not write - even for discussion, anything about underaged WGs

How old is consider underage in HK ?  
I am a magnet to.....


btw, read this from the post;
"male homosexual sex trades must be at least 21 years of age ".

Why 21 for male ? Because their anus only reach puberty at age 21?

There is a grey area with the age limit ... 16 is age of consent like what the OP said but legal age is 18 and there are points in law that I've heard of that takes both these into account - so please play safe (even you) and think of only 18+

I'm not sure what you meant by this. I was not about to say or post anything about underage WGs. Only as a warning and reminder about the legal age. By legal age, please go by the actual birthday (i.e. she isn't 16 till she fully crosses her birthday).

If the discussion is NOT to engage in underage but to highlight the laws, it should be ok, correct?

I understand that underage encounters cannot be discussed as per the forum guidelines, but he was just quoting the legal age from a government source.

Very good point. There was a very public case in Singapore that nabbed 40+ men, locals and foreigners, elites and serfs. I suspect that the laws in HK and Singapore are rather similar and based on the British common law.

In Singapore:  
Legal age for consensual sex with a female - Over 16
Legal age for paid sex with a female - Over 18

So what happens between 16-18? You cannot pay a girl aged 16-18 for sex. Nothing said about gifts. Basically it says that prostitution is only for females aged 18 and above. Many were caught because she advertised as 18 but she had not crossed her birthday.
That's why I was checking about HK law and I found that site that seems to refer to the HK law very clearly about age 16.
As TwiceAweek's advise... stick to above 18.

reading this, I thought you were going to write something that will lead to discussions regarding underaged sex
talking about the age limit is of course OK ... so sorry, my bad

Thanks bro - i'm new to the HK scene and this is very useful to know
