This is a difficult topic for lots of reasons, not least of them that CF rules don’t permit one to provide advice supporting gays except in a couple of forums (liberal
http://www.christianforums.com/forums/whosoever-will-may-come-liberal.401/, Methodist
http://www.christianforums.com/forums/wesleys-parish-methodist-nazarene.365/, and the liberal section of Lutherans
http://www.christianforums.com/forums/elca-elcic.518/). Also, I’m not a parent. I do work with youth at our church, so I’m interested in this issue.
Homosexuality is controversial, at least in the US. Many Christians now consider it OK, but the majority still consider it highly sinful. That’s why Sabertooth asked you what your attitude is.
A few decades ago conservative Christian parents would often try to get their son to convert from gay to straight. They might push him into counseling, and in some cases effectively kidnap him into a very coercive program. Or they might simply turn him out. A former youth pastor in our church worked with street children in San Francisco. Many of them were gay kids who had been thrown out by their parents.
Today this is less common, in part because forcible conversion attempts hurt kids more than it helped them, and throwing them out of the house had obvious bad effects. Thus the approach that responsible conservative Christians use will be a lot less forceful than in the past, although they will still try to convince the child that it is not God’s will for them to have sex with another person of the same sex.
I don’t know whether you’re aware of the political conflicts over this issue that have been happening in the US. Counseling that tries to convert someone from being gay to being straight has often produced bad results. In fact, it is possible for a motivated adult to change their sexual orientation to some extent. But it’s difficult, the results often aren’t complete, and it requires a person who really wants it. In many cases this kind of counseling has made things worse.
Secular psychologists, and many Christian psychologists, now consider it unethical to do it for minors, because it's too likely that parents are pushing them into it. In many states in the US it’s even illegal to do this kind of counseling with minors. I don’t know much about the culture in Hong Kong. Things may be different there.
I looked at web resources for this situation. Somewhat to my surprise, advice from the very conservative Focus on the Family and a liberal secular source were surprisingly similar:
http://family.custhelp.com/app/answ.../~/responding-to-teen-child-who-says-he’s-gay
http://www.psy.miami.edu/comingout/coming_out_art.phtml
The main difference is the Focus on the Family assumed that being gay is not acceptable to God. Thus they will try to connect the gay son with counseling that will push him in the direction of changing, or at least being celibate. A secular source will try to connect him with resources within the gay community. And a Christian group that accepts gays will try to connect him with Christians that accept gays.
I don’t think that in this group I can be more specific about Christian sources that accept gays, but in the forums mentioned above that would be possible.
From what I can tell, almost all churches in Hong Kong are strongly against homosexuality. If your son is involved in a church, please make sure you know your church's attitude before talking with anyone in the church about this.
